Describe the bug
Every time a rank up of the "COMBAT" skill occurs whilst the player is actively blocking with a shield it will crash the server and create a server crash log. Issue was reproduce 100% with Skeletons, spiders and Zombies.

Expected behavior
Game doesn't crash when blocking upon ranking Combat skill.

To Reproduce
Steps to reproduce the behavior:

1. Create a game and give you a shield.
2. Spawn or locate a zombie.
3. Keep blocking and let the zombie attack you until you rank up combat.
4. Notice that the game crashes.

Versions:

• Minecraft: 1.19.4
• Loader: Forge 45.0.22
• PMMO: 1.19.4-0.0.1

Additional context
I do use several other mods but it never crashed before installing this one when using the shield. In addition i can reproduce it 100% of the time.

an updated version is being built right now and should be on CF/Modrinth in about 20min

Just downloaded the new file from CF and tried again, i was able to rank up at least 5 level without any issues. So far this bug is fixed on my end.
Thank you,
