Alright, I have reinstalled SCS, and the spellcasters act normally. (all of them until now)
BUT i've noticed something else scrolling through near infinity and looking at the DOS installing SCS.
It removed some actors, it said, and truly I went to Mutamins garden, where the hostile adventuring party is (those 4 that taunt you and then attack, Kirian, Peter, Lindin and one more.) Only 2 of them where present. (Kirian and Peter)
Also I saw some dialog files in grey. (look screenshot)

will this be a future problem, or is this normal?
If I have to do a full reinstall, can I keep the savegame by copying it into the fresh install again?
