i was in my base and started getting anti-biter capsules and anti-creep i threw them to see what they did and they both worked i threw quite a few anti-biter capsules and it killed all biter bases on the loaded map but i discovered more bases and it no longer kills them for some reason it lowers their evolution factor but doesn't kill them at all unless they are in the poisonous cloud which wasn't something they needed to be in before for it to work, the creep now only lowers the evolution factor but well there is no more creep anywhere so it seems to still be working fine its jus the biter capsule that doesn't work anymore which is annoying since bases are getting quite big now
