I saw this a lot, but I feel like the only time i noticed it happening was on Labyrinth KP. So my questions are these:
Does it only happen on this guy because labyrinth gives you the extra time to stack that many (and also time to notice it)?
Does it only happen here because the labyrinth is "preventing" the damage, which in turn is preventing them from falling off?
I'm pretty sure the bombs should be viewed as damage from self, so it should not be affected by the Labyrinth prevention. But if for some reason it is being prevented, it shouldnt just hang out there and keep stacking either...
Did anyone else notice the massive time bomb stacks other places? Most toons died before the bombs went off, or from the bombs, as far as I could tell.
