Crash when Freeze spell touches the Spellbook

[whitebear60]

When trying to throw the freezing spell and it touches the Spellbook, it drops as item and than game crashes with ConcurrentModificationException.
To reproduce, hold the Frost Gem as an Alicorn, switch to shooting mode and cast the spell when holding the gem in your hand, so it will break the Spellbook.
(I don't know how to place the gem into the second slot, so I know how only shoot like this, maybe if I can replace catapult gem in second slot with freezing one, the game will also crash if I will cast that spell near the spellbook...)

Righto, thanks! This will be fixed in the next update. :)

Are you planning to release the mod on Modrinth and/or Curseforge, when it will be in release state?

Yes I will
