Reactor only ever maintained after breaking down?

[Sihmm]

I've got his issue where one of my fusion reactors is never maintained until it fails and stops producing power, which causes quite a shock to my grid. Plus it always seems to take ages to get fixed after failing, putting further unnecessary strain on the system.

• It's covered by three drone hubs, all with Low load and usually always with 30-40 idle drones sitting around (as it's near my rocket loading zone).
• It's right next to an electronics depot that's kept stocked with enough parts for the maintenance.
  
• Its priority is set to 'High', and it's the only building in that area with High priority.
• I found a 'request maintenance' mod and downloaded that (the game is otherwise unmodded), and if I catch it in time that works - but as soon as it breaks down the button is greyed out because (I presume) the request is already queued.

It's not hard for drones to reach or anything - it's only a couple of hexes from the nearest of the three hubs and drones often idle right next to it. And it's not like it's only happening when a rocket lands and the drones are busy - there are enough drones that even when a rocket does come in there are still a few left idle. When it does break I have to sit there and watch 30 drones sit around doing nothing despite the parts and the reactor being right next to them.

Any ideas?

Machine Parts? That is your problem. Look again.

Oh, that was just a mental typo. It's right next to an electronics depot, and I'm sure it's the right kind because I watch the drones picking the parts up and going to the reactor to service it - just after an agonisingly long wait.

It's an issue which is being replicated through other parts of my colony too and I don't know why. Buildings are breaking down instead of being maintained in time despite ample resources and free drones.

While tedious, you can select a Drone and pick up the needed repair material and tell them to FIX the unit for one units worth of repair. Pretty sure anyways...
