Weird undetectable bug in my ability

[Drain Pipe]

I've been combing this ability for a while but for some reason i can't find a bug that cuases one of my dummy units to spontaniously die

every time at one point, ususally when i cast and it hits enemy units with enabled attacks, the right "fan" missle dies and just goes away so i don't lnow why since i only have 1 function that kills and removes it

dont remove the dummy unit instantly. either wait for 2 seconds or add a 2 second expiration timer.

actually, that doesn't matter you can remove em any tiem you want like that. problem was it was conflicting with seemingly inactif triggers.
