Hmm, I'm running into trouble after accepting a Rover mission to chart Kerbin. The completion counter hangs at 37%, and anytime I mouseover the contract button in the top right, the game hangs for a few minutes. Checking the task manager, I see that the memory usage to KSP is going up with the cpu pegged to 50% (i.e. all of 1 core). After a few minutes it'll start working again, but by then it will have allocated anther 2-300k of RAM. Over the last hour of playing, I've got 1 GB extra memory allocated in this way. I checked KSP.log, and I get a bunch of 'Skipped frame because GfxDevice is in invalid state (device lost)' while it hangs. I hadn't seen any of these problems before starting to work on the rover contract, though I have had the mod installed for a few days (I just unlocked rovers today). Any ideas on what is going on for me?
