Question about spellbook

[HerlySQR]

If I have an item with the spellbook and some of its spell remove that item, can cause crashes or desync cast that spell?, I ask this because with my map after 2 players used that spellbook they just leave and I'm not sure if that is the reason.

I tested and didn't happen anything, so I guess they just rage-quited XD.
