Warp Stone isn't allowing me to teleport to waystones in the world. No GUI appears

Same here. When clicking, get the following dump in the log: https://pastebin.com/YcBpNkL2

Also get crash to main menu when breaking/placing new stones (after the above bug procs) https://pastebin.com/tkJRGNqy

On this line, for whatever reason, "hand" seems to be null? I'm not 100% sure of this, but I'm about 95% sure. I haven't encountered the error yet. I'm not sure how hand would end up null there either, but I traced it up at least to here without seeing any way of it getting corrupted (ie. it probably was null before reaching this point somehow):

As far as I can see there is no code path that could lead to hand being null, at least not with any other coremods/Sponge messing with it. Is this issue still happening?

Also I believe Termime's issue is a different one, since there the error seems to occur before the list is even shown. Would need a log from that one as well.

Sorry for the late reply. this issue is still happening.

Maybe it has something to do with vivecraft?

Does this still occur in 1.16.x?
