My friends and I were having a blast playing this game until yesterday, when no matter what map we were on, or what we did, eventually we could crash. After a lot of troubleshooting and general testing I narrowed it down to removing walls through either a Shard or the Prop Snatcher. This rendered the gamemode completely unplayable and I was wondering if there was any way to fix this as it's affecting everyone I played with, not just myself.

Some of my error messages:

If you can give me any help it would be greatly appreciated!
