I currently have the 8.5 version, and I've run in to a condition which reliably causes the game to crash to desktop for me:
I am on Turn 153, on Ganymede, and one of my mines has run dry. I've bulldozed the subterranean shaft structures, and attempting to bulldoze the surface mine structure causes the crash.
Additionally, some feedback:
Having a delay-based or right-click tooltip pop-up for the various structures at the bottom toolbar would be immensely helpful. At least to list the building's costs, but also descriptions of their various functions/purpose. I've played enough of Outpost 1.5 to muddle through, but the learning curve for this remake would probably be quite the barrier for any players unfamiliar with the premise.
