when you press shift on the 1.16 version, the entire game freese as string nbt cant be converted to compound nbt

The game crashed whilst rendering screen
Error: java.lang.ClassCastException: net.minecraft.nbt.StringNBT cannot be cast to net.minecraft.nbt.CompoundNBT
Exit Code: 255

If this is still relevant in the newest version, please open a new issue

for extra info, i got this crash using the brass modpack

Same issue, any update on fixing?

Also using brass and getting same crash. seems holding shift while tome is in inventory can cause it and do not need to be using tome.

A user of my modpack just reported a similar issue in Griefed/Survive-Create-Prosper-4#3. The user said:

Semi-regular crashes when mousing over or transferring items in inventory to a chest. So far the most recent was holding shift over bitumen collected from bitumen ore. Same type error in all cases.

I can replicate it by shift-hovering over the Akashic Tome in the players inventory. See hastebin https://haste.zneix.eu/ipolakiqoj.rb

Further tests with a previous version resulted in no crashes occuring. So, the crash occurs in
Forge 36.1.16, Minecraft 1.16.5, Akashic Tome version 1.4-16,
but not in
Forge 36.1.16, Minecraft 1.16.5, Akashic Tome 1.4-15.
Hope that helps!
