Hi. SS2 crushes on deck 4, always at the same place. I do four quests on deck 6, and get back on deck 4. It crush always on the crridor near the System Administration.

zip up your ss2.log and crash.dmp, and make them available somewhere (gdrive, ideally). perhaps add a save right before the crash, if it's always the same place.

using just the default GOG build of the game?

GOG biuld. V2.48

the ops2 save data is corrupted. go back to ops3 quickly, exit the game, and delete the ops2.MIS from the save_14 folder. run the game again, and load it - you should be able to return to the ops2 Xerxes room and not crash. this will, of course, reset the level to its default state - not an ideal solution, but you should be able to continue with your playthrough.

Thanks. ITs work.
