Spells Disappearing, Change Spell Button Not Working

[morpheus562]

I seem to have an issue where memorized spells will not return after resting. I.e. I have 6 castings of Stoneskin, I use it which brings it to 5; however, after resting it remains at 5 instead of going back to 6.

The only mod in my installation is this one and testing was done by creating a character in BG2EE ToB.

More testing: pressing the change prepared spells option refreshes existing spells instead of allowing me to update the spellbook. I have to hit this button 2 or 3+ times before I can edit spells. Additionally, it no longer allows me to cast Stoneskin or Mirror Images even when I have them memorized. It just doesn't show in the spell menu.
