Hello guys, firstly I want to tell you that english isn't my native language. So here is my problem, i want to go in the midden for the quest of mastering restoration, but my skyrim is making an infinite loading screen only for this part. I tried using the trapdoor, the console, unistalling all my mods , changing my ini files, using safety load... But there is nothing to do my skyrim just don't want me to go in here. If someone can tell me how to fix this, it could be really nice
