Kerbal Space Program

I went to Mission Control to look for new contracts and discovered that several that I'd been working on were no longer showing up in any of the sections. After looking on line I saw that others that had reported the problem seem think it was somehow related to working around Minmus or some other planetary body. I had a mission outbound to Minmus, and one returning from a solar orbit, but both of them were several game days out from needing my attention. All of the contracts were several game years away from expiring. I had a save point from the previous day showing 8 contracts, but now all but one of them was gone. Between then and now all I did was complete a single contract to do some observations on Kerbin, and my own mission to expand my orbital platform, as well as played around with a couple of SSTO flights. The only new mod I've installed recently was Stage Recovery, but I'd done that about 3 or 4 days prior to the contracts disappearing.

Although it meant losing some of my work, I restored from the save point about three days ago and proceeded with my missions. So far, the contracts that had disappeared previously are still there.
