Mob can spawn with a glitched block during gaia guardian 2 fight.

[Fatcow007]

Description

Mob spawns with a glitched block (purple texture) in hand, which can be dropped as an item.
Hovering over the picked up item in inventory will crash the game, causing "java.lang.NullPointerException: Rendering screen"

Item shows itself as "air" block when viewed through external tool (NBTExplorer).
Also, item disappears on game reload.

To Reproduce

1. Start the fight with gaia guardian 2, progress until mob spawning phase.
   • Unsure if only mobs spawned from gaia guardian 2 can produce this bug, but it is how I encountered & reproduced
2. Mob spawns with broken texture (purple checker) block in hand. Kill and obtain the block.
3. Hover over the block and crash.
   3-a. Restarting world will remove the glitched block from inventory.

Wither skeleton spawned with glitched block.

This is probably same issue is here, but thank you for the investigation! I think i could fix the issue next patch version.

For now, you can try to remove file config/malekremoveregistries.txt and this may fix the issue.

UPD: Try to remove only line botania:elementiumsword from that file and report if this fix the issue. You will need to restart the server.
