I testet this on my map a few houers long. When I attack the biters in huge groubs the game run normaly. When a few Biters stants by the repairwall and make a lot of damage the game slows town. I think this goes along with the partikels.
Have anyone the same problem?
I have that same problem, but it only occurs when the cloud is active in decent quantities at the same time as biters constantly hit those same walls, if the biters die fast and leave the walls with clouds alone the game is fine. Maybe a way to only start repair after a delay of being damaged would help?
