[Bug] Co-op Slow Motion on Custom Difficulty

[Yokami]

I've just broke a save because the game increasingly slows down (I'm at ~0.1x now) if there are too many mobs (caused by increased enemy wave multiplier or difficulty) when a horde comes, but happens only when on coop mode, slow motion is gone when on singleplayer in the same save.

I've even tried uploading the save to a friend to test if the problem was my PC, but to no success.

Needs fix ASAP, cuz not only there's no fix to that, there's no way to change diff mid game, lol.

I think its how fast you and the other person can stay in sync. We got this too. I'm happy it never disconnected though!
