Incompatibility with Pixelmon

[lizardguts73]

When trying to place down any of the ultra wood signs from pixelmon it causes a crash and locks you out of the world until you uninstall either crumbs or pixelmon.

Expected Behavior

The game shouldn't crash when placing an ultra sign.

Current Behavior

The game crashes when placing an ultra sign.

Steps to Reproduce

1. Have both pixelmon and crumbs in a modpack.
2. Make a new world.
3. Go into creative mode and get any of the ultra wood signs from pixelmon.
4. Place sign down.
5. Congrats you crashed the game.

Context (Environment)

This bug has prevented me from loading into a world and i had to sort through 600 mods to find which one was causing the crash.
Minecraft 1.16.5
Forge 36.2.39
Crumbs version 1.0.7
Pixelmon version 9.1.3

Hey, Crumbs is in a hiatus right now and is practically dead unless a miracle happens.

However, I took a look at the crash report and it says nothing about Crumbs in it. I expect that this crash is due to a combination of a few mods in that list with Pixelmon being the main problem, not Crumbs.

If you can get this crash to happen with just Pixelmon and Crumbs installed and send that crash report, I would be happy to take a look at it

The mods by themselves work fine its only when combined and when you place the ultra signs from pixelmon that it crashes.
