What happened?

Anytime I am in the Pyramid Structure in The Other, when I get to the second floor the game crashes. I tried completely removing the dimension and re-creating it, but am having the same effect. The only way I can get back in to the server is to use NBTExplorer to modify my dimension back to the overworld and re-upload it to the server before restarting. Otherwise, it just crashes immediately upon login.

Other details that may be relevant are the armor/weapon I am using. They are as follows:

Helmet: Vibranium
Enchants: Protection V, Mending, Unbreaking V, Respiration V, Aqua Affinity, Insight V, Mana Regen V
Socket: None
Chestplate: Vibranium

Update:
Wither Skeleton in Overworld caused the same crash.

I'd like to add that the server my friend is running recently encountered this issue as well. Getting attacked by wither skeletons has a high chance of crashing the game. it also caused the servers level.dat file to corrupt. My friend send me the world file to fix which I did after some experimenting which is how I found out about the corrupt level.dat and I tried it in single player to test it as well. Getting hit by wither skeletons in The Other and The Nether both causes crashes.

Have some thoughts, about half year ago i played with friends on hosting, and our playthrough ended due to server crashes with problem of ticking entities {including wither skeletons}. Now we want to try again, i tested mod to solve this problem, and it probably can help, unfortunately this is only workaround, this mod named "Neruina - Ticking Entity Fixer"
