Whenever I use the chat in the Lifeboat server (that's the only server that I know is working right now, but that's an unrelated issue), there's a chance that my game will freeze up and crash. This is really inconvenient because I like being able to chat with other players. This doesn't seem to happen in single player. It once froze for a moment in single player, but then started working a couple seconds later. The first time it froze in a server, it froze my whole computer along with it and I had to hard reset (holding down the power button until it turns off). If anyone else is having this problem, please explain it in the comments. Thanks.
Update: Most other servers seem to be working now, and this problem is happening on those as well.
Update: This is still happening on the Better Together beta and it does happen in singleplayer.
