Same thing here, same versions.

VanillaFix crash dump

Just looked at the code and I can't see how this can possibly happen, but I will attempt to reproduce it. Does this happen every time you try to open the handbook or just sometimes?

It happened twice while I was playing will go and try again to see if it still crashes and give a new crash report

Crashed again in a new world.
I just gave myself the book to test.

It's No Recipe Book causing it.

@Circine that's very helpful, the crash is definitely recipe-related

I have the same error, but (for possibly unrelated reasons) the crash quits the launcher, too, so I can't get a log. It may not be No Recipe Book, however, because I don't have that mod.

Here another crash report ^^

@Apotrox That's not the same bug, it's actually a duplicate of #36, which was fixed in wizardry 4.1.2. I can see you're using version 4.1.1 so please update your wizardry to 4.1.2 and it will fix your problem. (In future, please check you have the most up-to-date version before posting here!)

This may have been fixed by the handbook rewrite, it's a very old issue anyway. Please reopen if the problem persists.

@Electroblob77 I also encountered the same problem
