Hi there,
Few days ago I have purchased TerraMaxx. I was using it for only one day just fine, it then happened, though, that at the start of the next day, when I set the season to 'Winter' it then switched back (after like one second after having finished loading that season) to 'Default setting'. After it has finished doing that it once again started loading the 'Winter' season and that the whole time. The only way I have found so far was to quit X-Plane through the task manager.
It started happening out of nowhere.
