well, after reinstalling the whole game and all mods and installing Dustil Restoration last, everything works fine, no Dustil duplicates, closed doors, all cutscens play normaly.
the file responsible for this door is dr_kevil_dor.utd, i just made it open and put this file in override folder, using KOTOR Tool, thow i have another problem now. after i went through this door i had a scene, where Dustil follows, then i fight my evil clone and Revan loot the room and all i have left to do is leave the tomb and the quest doesn't proceed. i've done sith academy before going in that tomb. Where should i have proceeded with that quest? in the academy, in the room with Revan or somwhere later in the game?
Is there any way i could fix this door myself? i have KOTOR tool.
Which door is it, what it's file name?
Edit: its dr_kevil_dor.utd, i just left in open and put this file in override folder
