My game is starting to glitch real 1-10 seconds. Ups is 60, and then drops to 45 as a single long frame happens. I think it is TD, but haven't proved it. It is becoming worse as I add more request/supply nodes.
I think I found another mod that was responsible for the worst stalling. There are still small glitches, but they are not serious enough to be able to tie back to a cause. Please consider this closed for now.
