Describe your issue
Industries warehouse / resource storage import still bugged. Still overimports until overfilled.

What is your game version?
Latest Financial District

What expansions do you have installed?
After Dark, Snowfall, Natural Disasters, Mass Transit, Green Cities, Parklife, Industries, Campus, Sunset Harbor, Airports

What mods are you using?
Vanilla unlimited money, unlock all, unlimited oil&ore mods.

Please explain your issue is in as much detail as possible.
Warehouse and resource storages still overimports since Roads and Vehicles updates.

In addition, watching the import trains and trucks arrive and getting to the storages I've concluded a few things that worsen or lessen the phenomena.

What worsen the overimport are:
- Having import sites (like cargo stations) further from the storage. This makes goods take longer to arrive and in the meantime, the storages just order more and more.
- Having more import routes. It seems storage will import via many routes, and probably it orders enough from each route for 'just balanced' storage. If you have 2+ import routes, the overimport gets worse and worse.

What lessen the overimport are:
- Having bad traffic and generally bad city plan. This causes some import trucks to despawn before getting to the warehouse, relieving the problem.
- Having local production of said resource. In this case there may no need of import at all.

It seems this bug penalizes good city design (having well-established cargo network and good traffic) and would barely be noticeable in poorly managed ones.

It also only affects import-reliant economy.

This bug is game-breaking for players who can't stand seeing their traffic below 90.

Until this is fixed I'll be playing other Paradox games, no more CS. Needless to say the last DLC I've bought was Plazas and Promenades, I won't buy anymore and will encourage everyone to do the same.

In the attached city the problem is minor, because there is only cargo station and it's right in the warehouse/industry district. (so few import routes and also short routes). Road is also not very good so I've seen some trucks despawn before ever getting to the resource storage. Yet it still happens.

Can you replicate the issue? If yes, please explain how you did it.
This is my attempt to minimally replicate the issue. Just start a new city, build a resource storage and some processors that use the resource. Connect cargo routes. Get all the services like power and water running and then wait. (I've done all this and waited for the problem for you)

edit: Lakefield 2 is another city on the same map where I verified my observation by increasing the 2 amplifying factors, far and many cargo stations, and also designed better roads to decrease truck despawning. Comparing Lakefield (1) and Lakefield 2 you can easily see the effect of the bug is much more prominent in Lakefield 2.

I added Lakefield 2 as another city on the same map where I increased the amplifying factor. Farther and more cargo stations. Also longer buffer roads so trucks don't despawn as much. You can see the problem is much worse on Lakefield 2.
 
I'm afraid I have no update on this, we're still investigating the issue and don't have an ETA for at fix at this time.
 
I can confirm that the problem gets worse the more import options you have. Having just a highway outside connection brings a whole load of trucks but settles down quickly. Adding a cargo rail terminal with an outside connection doubles the number of trucks. Same for cargo harbour and cargo airport.

I expect it now so I try and plan accordingly. Whenever I build an industrial area, I only place the main building and whichever storage building the area needs. Only once the import frenzy has stopped and the storage building vehicles have stopped exporting the imported products, do I build the extractors and processors. You have to be very careful to have enough extractors to handle the processors otherwise the storage will go down too quickly and the frenzy begins again. This happens quite frequently when working with the smallest storage buildings.

It is workable but is a massive pain, especially when decided to upgrade to a bigger storage building...
 
Right, I hate not being able to finish my cities and I don't expect a quick fix, but lack of acknowledgement of existence of this bug in patch notes is unacceptable to me.

Strange... your wood chip storage is also overimporting. I thought this bug only affected ore, oil and generic goods. Does agriculture and forestry storage get overloaded if there are imports of any kind? I haven't seen that in my city.
 
This is driving me nuts. It basically ruins the game. Has anyone found an easy work around? Any maps that work even though others don't? Do old saved games have the same problem? (Mine seem too). I tried a fresh install but no luck.
 
To other players following this bug: I've found a mod that fixes this issue.

Transfer Manager Community Edition on default settings will fix the overimport. (I have yet to experiment with reducing its functions to bare minimum, but I have tested that the default mod settings will fix it.)

To CO devs: Something among that mod's many lines of code can fix your problem.
 
ugh just confirming here that after waiting a long time for the intercity train checkbox to be fixed, i load up the game only to run into this bug almost immediately.

outside of using a mod, i've found that hooking up a storage building to a road, then immediately destroying the road and letting the game run for a while with it disconnected, seems to cancel all the imports. (see below post)

otherwise, even if i immediatley switch the storage to "Empty", i still get a bajillion imports. It's almost catastrophic if I'm not setting the building on "fill," the smaller warehouses simply can't export all that capacity fast enough if I'm even producing even a little, and my entire logistics breaks down as freight trucks for all my warehouses and producers end up having to export and get used up.

ughhhhhhhh never mind my last post. i thought destroying the road and running the game for a while would fix it, and it *does* cancel the imports, but as soon as you reconnect it to a road network suddenly you get a bajillion importing trucks again. i'm scared to load up one of my existing cities because if they dip even slightly below the "balance" threshold for importing, the entire industries logistics might breakdown from being overwhelmed with imports.

how on earth do you break an old DLC like this so thoroughly...

i was looking forward to playing again now that the intercity trains bug is fixed, but looks like i'm going to have to shelve the game again
