Saving and loading seem to work fine. I did spot a possible bug though; I picked up a Bow Spell, then left the room, fought some monsters and came back and there was another Bow Spell in the same spot. I haven't been able to reproduce that after the first time, however. Possibly there were two Bow Spells on top of each other to begin with and I missed the second one the first time I was in the room, although I don't think so.
