I wanted to go onto Discord so I could mention this, but as you can see here, I can't get on. I shall post it here, instead.
I was playing on the Ghorkov part of the expansion pack, and I noticed my Tekh-Trak was moving quicker, more like a Speedy, then back as a Tekh-Trak repeatedly. The Host Station icon, flashing on the map, was flashing too quickly, as well. I saved the game and closed the programme, restarted and my computer and tried again, but it didn't start-up. I put it in compatibility with XP SP2 and to start as Administrator, then it started but my saved games were deleted.
I was thinking about setting the programme's priority, in Task Manager, lower, in case that was the cause (which didn't matter previously), but going out of the game (Alt+Tab) usually means I can't get back into the game, with it changing screen resolution a million times.
I don't know why this would happen now randomly all of a sudden. I suppose I don't mind starting the expansion game (Ghorkovs) again, but has anyone else experienced this, and/or possibly know what caused it?
P.S. I presume the problem would occur on the main game, and the Taerkasten game, as well, but I experienced it only now after finishing the main game and before playing as Taerkastens.
