Well, basically my problem is that i installed couple of mods (Some with NMM and some manually) and now i can't get through the opening scene where the alduin attacks the helgen. I run inside the tower and alduin should break the wall but that doesn't happen. Sometimes i hear him flying around the area and sometimes i just start absorbing the dragon soul (So sometimes he dies in the opening scene). That still really wasn't game breaking for me. What really breaks the game for me is that the guy i choose to follow at the start, won't come out of the first dungeon. He'll walk all the way to the end and just stop walking. So i can't get the first quests from him or anything.
I've tried to install the mods one by one (from NMM) and sometimes it happens and sometimes it doesn't. I find one mod that breaks the game, uninstall it and then the next mod in the list may break the game again. So i guess there some compatibility issues with one of the manually installed mods.
Is there any way to see what mods i've installed manually? Or is there possibly a known mod that does something like this?
