1.2 quick save hangs game and corrupts career saves

[PGTART]

So i decided to go scratch again, without mods, and it is that i lately encounter more game hangs then usual.
so far in a day time
- hang when trying to go out of contracts, i clicked the top top icons to leave, icons got away and i was unable to leave that room.
- did a mun mission, as mechjeb isnt jet available (how is this game suposed to be fun without it?).
  so while doing things on sight, and saving games in between i hoped to finally land on the mun.. but after save, you guesed it game crash GUI non responsive.

 and like my previous hang, it did not only 'hang' that single game, all progress was lost esentially having to create a new game.. to start from scratch again !

-- this makes me wish to revert to a previous version or to ask for a cashback or so.

Hi @PGTART, if you could take a look here and rustle up your game logs and system specs we coul dtry to figure out what's wrong.

well as for now i revert to a older version, the program has send crash statistics
i go back to a saved game directory as KSP without mechjeb isnt nice to play.
