Minecraft version: 1.12.2 [change as necessary]
Wizardry version: 4.1.2 [change as necessary]
Environment: Singleplayer [delete as necessary]

Issue details: Unfortunately, the game crashes upon the wizard book being used after I change the key to "Next Spell", similarly to #45. The mod version is latest, but it still happens. Is there anything we can do? Thank you, electroblob

Other mods involved: Roguelike Adventure modpack

Link to crash report (if applicable): https://pastebin.com/VN8CVzP2

I was using a novice wand and made my next key the comma key and it made my game crash

What did you change the next spell key to? The crash report doesn't look the same as in #45, but I could be wrong.

I changed it to "". I tried a couple more like "insert" and etc. but I think it didn't work

This may be fixed by the handbook rewrite in Wizardry 4.2. If not, please reopen this issue.
