Hmmm, which patch is it? It reminds me Daggerfall very strongly [img]graemlins/hehe.gif[/img] I haven't seen the effect in 1.02.0702

If the problem is caused by importing buggy code from Daggerfall then you must watch edges of any kind. You usually fell into the "void" in Daggerfall in the following cases:

(a) When you climbed a wall - you fell to the void when you reached the upper edge of the wall.
(b) When you jumped down carefully, especially with a slowfall and around an edge in the wall - the edge "caught" you and immobilized you. No chance for release.
(c) When you tried to jump through a "narrow profile" in a passage.
(d) When you swam (or flew) near a ceiling - the ceiling caught you as in the case of carefully jumping down.
(e) At certain known places, for example, there were two "black holes" in the small ship, which you must avoid when you moved through the ship. These places were fixed and "work" in every game run.
