I have an issue where, at times, after some contract offer declines, I will get the Scansat "Biome Scan of Kerbin" contract offered for about 1/3 second, then it quickly disappears. I have already been offered and completed the Mun and Minmus Biome Scan contracts. I have not yet put a Biome scanner in Kerbin orbit. How can I troubleshoot this issue? The Alt-F12 debug log nor Contract screen offered any insight.
