Only happens rarely when u have so many mobs backed up so far w/ slows/freeze/etc. + some special thing happens where the game REALLY freaks out and all of a sudden you are in the "seconds per frame" category.

Has happened to me twice and this time i'm reporting cuz, unlike last time, this time, the mobs somehow kept procing while the game was frozen and i went from like 2 leaks to 20 and quickly lost a killer endless run on catacomb.

Don't remember how things resolved last time but it wasn't like this. Apparently enough mobs died or the collision unglitched itself or whatever and the game resumed normal speed and I died the normal "fair" way.
