I tried it on the old win 10 version and it does give me the "dash engine" without freezing. Just to mention it and make sure, I was playing the current latest SAGE version (it's the version in which the freeze happens). The screenshot is the text prompt when the freeze occurs.
1st run: I might have sequence break by entering lava abusing the nano shield, when nearing the end, mark says I still have some bioweapons to collect, then the game froze upon getting the jet engine. 2nd run: I tried to follow the game events, got pretty much all upgrades (at least that I'm aware of), it ended the exact same way.
3rd run: I ran through the early game getting all 3 required upgrades to go see mark as early as possible, same issue yet again. Might be just a me problem but I really don't know why this keeps happening in seemingly different situations. Is Mark supposed to say that everytime or does he have another dialogue?
