When teleporting across dimensions an error is often thrown

Can confirm.

Cannot reproduce in 25w10a; is this still an issue?

Yes, I encountered it when going through an end gateway in the end.

I just noticed the stack trace is a bit different, is this the same error?

It looks like the same error. The only differences are the obfuscated class names, which do indeed change in most cases when a new snapshot comes out.

Ok, I see.
