Kerbal Space Program

Quicksave in dangerous situations (such as fast movement low over terrain) is still new, so bugs are to be expected.

I found the problem, and I believe it is an extension of #2049.

Vessel PID fddf7dcdea6e439aa4982659b34447ff, name Kaeris II T Debris is reported as LANDED, with orbit:

SMA = NaN
ECC = 1
INC = NaN
LPE = 108.077215273401
LAN = 15.5781035258577
MNA = -8.40714670366795
EPH = 469836666.438818
REF = 12

These initial messages you found (up to line 5230) are caused by what remained in the persistence file after the game crashed the last round. They don't cause and permanent problems if all I do is just load the quicksave. If you try to load the quicksave once in a clean save, you'll not have them. If you restart the game and try to load that quicksave once again, they'll be there. But the behavior of the game does not depend on it (unless you try to fly one of those ships from tracking station).

The real issue starts on line 5622 which is immediately after the quickload. At that time all ships from previous persistence were already removed.

The NaN problems might be related to #2049 but the ship explosion after quickload is definitely not. It might be related to #1601.

Oh and another funny thing on Pol that might be related to the issue is: if you plant a flag on Pol, then quicksave your Kerbal as it is standing beside the flag, then quickload, you'll find the flag several hundred meters above surface.
