Special Effects Disapearing=(

somtimes the special effects on some units disapear for somreason? how would i fixed this.. maybe its a trigger messup? or should i put each hero in a diffrent unit variable to fix it?

It's most probably a trigger mess-up.
You most likely has got a Unit array variable, right?

If so, you should check that it affects the right hero, and that it (the trigger) triggers when it's supposed to.
