ATM9 Server Crashing in Other dimension Dungeon

[CozyRocket]

I've got a server running 9-0.2.46 that is crashing when a player is in the Other dimension dungeon area. I'll try updating the server to the latest version, but from what I've read in the below its because of a mob spawning? I'm not sure I'm not an expert at reading the crash logs.

Below is the crash log:

IDK If adding my comments helps, but the same is happening on our server. Version 0.2.43

Currently next to a wither skeleton spawner in one of the hallways. It has crashed 3 times in this area. Requiring editing forge config to delete ticking entities, restarting, loading in, shutting down and turning the setting back to false.

I had just fixed it, walked down the hall for the next set of spawners and chests and it crashed again. I'll now ask folks to avoid the area.

I get a similar crash when being hurt by a Wither Skeleton, even one naturally spawned from the Nether or from a dungeon in the Overworld. Can you please attach screenshots or NBT dumps of the tools and armor you had at the time of crash?

IIRC it's always involved Wither Skeletons, at least the last 3.

Couldn't easily find how to NBT dump, but here are screenshots of what I had on.

Miscellaneous artifacts. If an NBT dump is better and you can tell me how I can give it a try.

[James103]

For an NBT dump, try running data get entity @s, then post the resulting output from the logs.
If the NBT data is too large to post, run recipe take @s * then try again.

[katalyste]

Ok, here are the results of that command. after recipe take @s *. Otherwise the log more than quadrupled pastebin's max size.

Same issue for me, wither skeleton is ticking and crashing the server upon joining. Gonna try switching to peaceful to despawn it
