Defeat Trigger Bug?

I haven't been making any maps for a while, and since I started making one like a week ago, I would like to ask a question, I think I remember something about the "Game - Defeat Player" trigger, can't really say what this bug did, but it was pretty bad iirc, so my questions are:

1 - Is this bug still around, if this actually was a problem, I might be wrong...
2 - What does the bug do?
3 - What's the best workaround to solve this?

The bug was fixed on 1.15 I think, it was just a glitch that disabled the interface of players that didn't leave, but it was solveable back then.

but using the newest patch you should have no problem

Ok, thx for the info, haven't made any maps since back then, but I've got the the latest patch and all...

Then you'll prolly be really happy with all the new Triggers and Abilities since... But also some drawbacks *Curses Blizzard for making "Orb of (Insert Element)" require you to target the units yourself, or issue attack move, else it wont work, completely ruined my TD... Meh...*
