Auto ban issue in Dimension Invasion

I see. All I know is that that error can also pop up when fighting Von Leon with the spawn maxed. One of the problems in that situation is definitely a memory leak.

There's a lot of party zone mobs at Dimensional Invade too, so that's the first thing that popped into my mind.

You may be right. It'd be pretty funny if Dimensional Invade summoned the exact amount of monsters to cause a memory leak big enough to crash the game when Blackheart spawns.
