Instead of bug searching/explaining/whining on this forum I was back to the core business of this game, building a track

I worked on a track I've started a while ago. I drove some laps and wanted to change a couple of bilboards.
I removed two 10-3-4 bilboards and placed two new 10-3-1's. When I wanted to change the skin of the first one, (using a custom URL) I found myself on my desktop again

Opening the track started as usual with a freezedetect: 016649FC
