This is the version that crashed my game.
Be warned, it completely unbalances the complete game.

I found the problem: I was trying to add four extra charging slots to the roboport, or at least that seems to have been the problem.
When i removed them i could load the save again like normal.

Also thanks for the quick help.

I've been toying a little with a custom mod i made, but when i tried loading the game without any mods yesterday it gave the same errormessage.
Edit: I tried it again today and it loaded correctly but removed many mod added objects.

The game starts fine but always crashes when i try to load one of my singleplayer saves. When i tried my other saves they all worked fine.
