Here's the weirdest:feel free to try!
I was riding Shadowmere along a path next to an oblivion gate. There was a town right up ahead, i think chorrol. I was following a scamp when it suddenly attacked me. I (still on Shadowmere) ran to the city gate up against the wall and faced the scamp, then dismounted JUST AS a fireball hit both ME AND SHADOWMERE! she was knocked out and i turned invisible! but my body was on the ground!!!
then i got back on shadowmere (still out-of-body) and rode down the path, only to look back and see my body AGAIN---floating in the air like it was on a horse!!
i walked under it, and suddenly it stretched out!! i was like WTF!??! O_O
then, i went back to the gate where only my shield was left, half-covered by the wall.
i passed under "my" body a few times, only to see it stretch 1000 feet!!! XDDDDDDDD
it's pretty cool to "just" control shadowmere.however, i tried going to other save files and they were invisible too!!
this was all fixed when i ejected and re-inserted the game.
Oblivion is the most amazing game ever made. Great job, Bethesda.
