this is what ive been looking for

looks like patchfinding gotta something like infinite loop when thereis lack of free tiles.Unfortunely way to fix it is reduce the amount of hordes in difficulty. long range explosives and killing melee monsters make a great job against lags.

i7 with 32GB ram lags a lot after around 90 days, CPU usage only around 10~15% and memory of max 2G...
running with 1070Ti... any chance you know how to fix the lag?
