I reloaded the game today, and my drow cleric has different spells memorized than what I selected last night (e.g he has darkvision prepared, something I certainly have no need of). With unlimited rests, not a problem; but something that should be addressed, nevertheless.
If you hit K as long as you're not in combat, you can change your prepared spells around, but yeah, if it changes on its own that's a problem.
