Kerbal Space Program

I see from your output_log.txt that you are running several mods, including KAC and MechJeb. The source of the bug could be one of these mods--try to reproduce the bug in vanilla and post again.

Can you list the steps needed to reproduce the bug? Please include a .craft file for an affected vessel.

Make sure you have some flights in progress (I had 18 while using the mod, 1 without the mods).
While in the Space Center, time warp at maximum speed.
At any time during that time warp, click on the Mission Control building and then leave the building.
Do this any number of times you want all while time warp is still at max speed.
Then slow down the time to 1x and use the Tracker to jump to any in-flight vessel.
Crash happens either while loading that vessel or when loading back the Space Center. It doesn't matter which vessel it goes to.

• I can't reproduce the bug following your directions, on career mode or sandbox.
• The .craft file you uploaded contains mod parts--my vanilla install says "[Error]: [ShipConstruct]: Trying to load Daenerys-Rover - No AvailablePart found for mumech.MJ2.AR202" in the Debug Console (in sandbox) when trying to launch your craft.

Please try to reproduce the bug on a fresh installation of KSP with standard parts. You might also try to remove whatever part mumech.MJ2.AR202 is referring to and try to reproduce the bug again--the problem may lie in MechJeb (I assume that's what the MJ stands for). If you can't reproduce the bug in vanilla, we should probably close this report.

mumech.MJ.AR202 is the mechjeb unit.

As of reproducing a bug fully on stock, let me go through the steps.

Please (backup and) delete the following folders from your KSP directory:
.\saves\
.\settings.cfg

Also delete all subdirectories and files except what is contained in the directories "Squad" and "NASAmission" in the following directory:
.\GameData\

You may just want to copy the whole KSP directory before doing this. I maintain a separate stock-only KSP installation directory specifically for testing.

As a note, unless this can be duplicated on a non-Win64 setup, it should be considered Win64 specific.

Finally, you don't need to compress your log files. HTTP uses gzip compression for transit (which has better compression than RAR) and the server likely does not need compression. Compressing files with RAR just makes it so people can't view them in their browsers. (As a note, of the widespread used protocols 7zip has the best compression ratio for most major data types, including text. There are a handful of compression formats that are superior, but most are obscure formats like lzop or experimental formats like paq.)

I tried on a fresh, vanilla install, and wasn't able to reproduce either. So I'll blame the mods and I'm sorry for wasting your time. I'll try to save my savegame somehow.

You can close this ticket.
