Carn Dum Bug

[Heurazio]

Hi guys,

DISCLAIMER: I play on PS3. This is a description of the level: https://guides.gamepressure.com/thelordoftheringswarinthenorth/guide.asp?ID=13180.

I have the following problem. I'm in Carn Dum and I already made my way to the courtyard (with the two metal doors and the lever). Nevertheless, my problem is, the two doors to access the lever won't open.

This situation emerged from a checkpoint reset after a defeat. In the first run, they open but after the defeat, they won't.

I already tried to restart the checkpoint (I just die on purpose), restart the game, and the PS3. Nothing helped.

Is there a way to just restart the level? I really don't want to start over again :-(

Any help would be highly welcome.
