I'm trying to create a poison (fart) cloud that damages enemies every 0,6 seconds and it should affect a group of enemies at the same time.
The thing is, it almost always leaves one enemy unaffected (from a group of any number of enemies) and it's always the one that as 0 / X as Z index. (I don't know what that could mean).
Sometimes -although veeeery rarely- the cloud affects everyone. I've tried shooting from every angle but it doesn't seem to change anything.
Here's a video showing the issue:
and here's a capture of my events:
Do you have any idea what could it be?
