Lastly: If you do get in touch I can send you test builds that may fix the issue. Since I can't reproduce it locally it's hard to say what triggers it. A random question: Do you have STEAM on your system?
Yes I do have Steam on my system, have not opened it for a few weeks...
O wow, I just tried opening it now with internet on and it worked. Not sure what the problem was but it seemed to fix itself.
Sorry for the false alarm/confusion and Thank you for the quick reply's and your work with this amazing game.
All the best :)
