KioM, I suspect that all these transfers of static objects in Heroes of Might and Magic V were implemented rather carelessly. For example, I had a case where a campfire within one level could be moved normally, but if I tried to move it from the underground to the surface, strange bugs started to occur. Considering that the bridge affects the surface geometry, Nival might not have implemented the geometry change during its transfers and creation using CreateStatic(). Perhaps, even after moving the bridge, it might still be possible to walk through the place where it was originally located?
