I have two heavi-watt joint plates that occasionally stop functioning. This is... quite troubling since they connect my power producers with my consumers. However, after struggling for a bit with it, I discovered that the problem can be solved if I simply save the game, quit, return. I don't even have to reload. So now it's manageable, although still annoying.
I'm only having trouble with those two plates, and I'm thinking it might have something to do with the way they're overlapping. I'll add a picture so you can see what I mean.
Steps to Reproduce
I'm not sure what triggers the problem, but it seems to happen after the system goes down, for example because the natural gas geyser goes dormant.
