Ok I've found two bugs;
1) One of the balors telekenisis spells does not have its name correctly identified and is using whatever string happens to be there, for me this is something like, "Oh so you need me back in the party, I think I have...". I have found that it is in the setup file that it is not correctly changed so it should be a simple, matter to change.
2) SPPR950 is an effect of standard true sight and is producing permanent modified script states on all enemies in the area (or the party if cast by an enemy), it doesn't need a modified script state as it effect is instantaneous and removing the modified script state fixes the bug. I have a copy of the fixed version of the spell, if you need it.
Would be nice if we could get these two bugs fixed in the next version.
