Time warp limitations

[THX1138]

I've got to do some temperature scans of Gilly to fulfil a contract. I entered a polar-ish orbit so I can start doing sweeps over the surface but the altitudes have to be quite low which means I can't warp time. The time to complete each orbit is over an hour. I switched to another vessel to enable the time warp and the lander in low orbit around Gilly disappeared, presumed by the game to have crashed into Gilly. It's going to take a great many orbits to complete this contract (most won't put me in the right spot for a measurement) and at 1 hr 30 per orbit, I'd rather play Garden Strimmer Simulator 2014.
