Please include as much information as possible in the description of your issue and include:
There’s a possible Backend error when switching from Superior Gaskets to Experimental Steam Capacitors when you have any existing charges with Superior Gaskets active.
I tried to reproduce this issue again, but instead I ended up with a stack of SG’s pressure and a stack of ESC pressure, both of which were active and kept charging the minigun. Of course, this wouldn’t work in a quest, however it’s weird and should probably be looked into.
