@Bienie That is even less script, so that's good : ) I thought acuity_tact to 0 would somehow change the behaviour of AI a bit and would be least noticable on zombies. Intrestingly zombies don't seem to need having StimEnable (14, 0) on the dead bodies to not see them. Could you test with only acuity_tact:0? It looks like that might be the only thing needed from my quick test.
