Hey,
Just recently encountered a major bug. When I start BG2 after character creation, there was this cutscene where two mages bein attacked by beholder and another mage yelling "you bad dog" then suddenly back at the dungeon, that yelling mage got teleported in the cage. Then stuck and no more after that, no Imoen that release you from the cage.
EDIT:
So I clicked on the Level Up button and then suddenly you remembered when you were much younger and the cutscene comes back to the old Gorion and the younger you.
EDIT:
So much randomness, the game is kinda somewhat....ruined with this megamod.
