Just as title describes - when casting any variation of Place Block with the Projectile glyph, it completely deletes the spell book from your inventory upon the spell's resolution (perhaps as if trying to "place" the spell book?)

Hoping this is fixed ASAP, very confusing.

This seems to be the case as well with casting Touch > Sensitive > Place Block. It seems to confuse the spell book as a block to place.

Edit: It also erases even spell wands.

Update to the latest version, this has been fixed.
