Crashed upon landing at a Celestial Gateway, and kept crashing upon logging in. Uninstalled optifine, crashed once, but successfully stayed in for the 2nd time.

I've had a very similar issue with, and without optifine. Removing optifine fixed the issue the first time, but the crash came back and didn't stop until the gateway was broken. I'm on the same multiplayer server as Vyraal1, if that helps.
