I'm doing something wrong, but I don't know what in the heck...
Problem 1
Floating doors and invisible building. Please note the interiors all look perfectly fine.
Some other glitching includes invisible clothing.
Object clipping...
And infinite falling...
I really just have no idea what to do. I've messed with this for hours upon hour. I stayed up late into the night, getting 2 hours of sleep before work, and I'm about to pull my hair out.

For anyone else with this
For anyone else with this problem, I solved it with the help of GrimWeeder and AndreyKva. They suggested I load Morrowind_ob.esm after Oblivion.esm. You know, like I was SUPPOSED TO.
Ever feel really, REALLY stupid? -_-
