That's along the same lines i was thinking too... because I tested to see what would happen without the mod installed and those same Trivial-level, test-part-while-landed, contracts all asked me to test on my home planet, Kerbin. So, it seems that Kerbin is sort of the default location for those types of contracts. And like you I was wondering if something with the mod was causing KSP to replace that "default" with one of the PF system planets. I'd like to poke around and figure it out but i just don't know enough about how the new contract system is programmed. I do hope we can keep PF CE alive, its one of my most favoritest mods ever
