It is running with stability for me. If you were installing a modb, dropbox of forum zip, did you remove the old mod or just overwrite it? You should have removed the old one. Regardless of how you are downloading (including steam), please delete the contents of the cache.From a first glance this looks very well done with a lot of effort put into it. However, right now it is not playable for me due to constant ingame crashes. The game crashes when I select to play with a higher time compression, when panning around the map while unpaused and in general when a lot of stuff seems to go on. It seems to me that the problem is caused by my pc not being able to keep up, however I never had that problem in other rather demanding mods like Geheimnisnacht. Any clues?
Another problem people have is if they are using the Units submod and they are lacking one of the DLCs that it calls for one of the units. Lacking the graphic reference is usually a crash to desktop. So if you are having trouble with POD Units enabled, try playing without that.
I routinely run the mod for hundreds of years at max speed for hundreds of years without a crash.
You might go slow at the very start up as supernatural traits are handed out to random courtiers on the 2nd day.
