That's good to hear. When my wife and I had the bug, it probably started around 100 hours into the game, but became worse and worse the larger the save file got. Around 150 hours we had to delete homeworld, which really sucked.
Hopefully someone else encounters it. If you want to have a look, see this.

It also links to my discussion with the maker of homeworld redux.
Maybe you can find something there to see what caused the bug, if/when it starts happening again.
