How big is your layout?
currently its 1920*1080, but at the other resolutions the result is the same.
Simple Games the problem is I'm not sure if it is a bug or if I'm doing something wrong.
calminthenight Looks like you are right, it depends on number of the creeps and the region size. I've changed the region to 16*16 and the bugs disappeared.
But the event of regeneration the whole map still takes about 7 ticks and the event of regeneration a region still takes about 20 ticks.
You can test this by changing both events to "pick random instance"
But in the real game there are more then 1 creep, thats why I testing on 1000 instances. Unfortunately, map regeneration for 1 instance doesn't take effect for all the instances.
