silver seed problem

[grungi]

working my way through silver seed i come across a pretty big problem, in the north section of the map, above the main outpost area theres a load of stairs down, 4 or so, if i take any of them the game crashes, it goes white briefly then cuts out to windows, no error message or anything, any ideas?

If you want, submit a bug report with a savegame just before you go down the stairs. If we can duplicate the problem, we can fix it.
