For the predatory bird quest, one of the bottles I'm supposed to get is embedded in the straw at the top of the lighthouse and I can't pick it up.

Also, the pass east of the Arcane Asylum is inaccessible, since a bridge that was there before has suddenly disappeared.

A bridge has disappeared? Please upload your savegame so we can see what exactly happened there.
Same for the bottles.

The bridge reappeared when I reverted to an earlier save. I've uploaded an old save of the lighthouse. I think both problems probably stem from my graphics card, because I've noticed other occasional problems with rendering objects.
