New patch (v81)

Hello, I've released another stability patch. This one is mainly about fixing a bunch of different crashes and some out of syncs that were reported to me since the game shipped. Hopefully with these out the way I'll be able to work on more interesting things soon :) Here's the changelist:

• Fix for terrain from previous co-op games sometimes being left visible when you start a new one (I think)
  
• Fix for character showing idle pose all the time instead of animating in some situations on online co-op
  
• A lot of crash and out of sync fixes
