Non-skippable cutscenes can be rather annoying.
I never had a problem getting to opponents (playing the Xbox version), and havn't seen that reported for random combat (several people hit a similar wall approaching the gate in Farglow, but lowering the graphics settings, or something like that, temporarily would let them get through).
I never ran into any objects that continued to rock when bumped, but a couple times entering caves/cellars baskets or vases would fall or slide out of place. I once walked by a crate in High Hall near the start, and it slid downhill like it was on ice.
Welcome to the forum.
BTW, you posted this in the Divine Divinity forum, rather than the D2:ED general
forum (there are a couple suggestion topics there).
