I love skyrim and I love improving it with new mods but it's now at the stage where I can no longer play it vanilla but the mods I can't bear to part with are clashing and causing regular ctd. I can't remember the last time I had a functional setup and seem to spend all my time trying to juggle mods to find something stable. A recent foray into skeleton replacers caused irrecoverable corruption. I run with about 30 to 50 mods at any one time and having to redo from scratch causes genuine pain.

Greatest modding disasters? And/or mods you just can't live without?
