Thx for reporting, I will investigate this tomorrow

Which book are you trying to insert?
There is a bug which crashes the game if trying to insert a wrong item, but I cannot reproduce this issue when inserting a "vampire book" ("Ancient writing")-

Does this issue still exist?

Closing because older than one month
