I've dug up my copy of the original Homeworld again, and was quite happy that it seemed to still work well on modern systems. I played the first 3 campaign missions and then left it. Today I wanted to go back to the game but now everytime I try to load the game from the auto saves generated at the beginning of the mission the game CTDs.

Oddly enough I can start a new campaign, or skirmish just fine. It just wont load from those saves.
