Kraft Size Unknown / No Root Part

[entropy--]

Hello,

I built a krane [0] to move my kolony equipment around, and the problem I am having is that, after building it, the next time I load it, it fails to load properly [1], [2], and, in addition, once this happens I can no longer load any other ships. A 4-line "Auto-Saved Ship.craft" file [3] is created in my "saves/.../Ships/VAB" directory, and, once deleted, I can load other ships and fly them, but the situation repeats its self is I load the krane ship.

I have re-built the ship multiple times, with minor variations, and sometimes I can "fly" it right after I build it (I *almost* managed to use the krane to move a piece of kolony equipment once!); other times I can not fly it at all (the map centers around the sun, and all controls, including the escape menu, are gone). Loading never works again before I delete the above-mentioned file, and I can never fly it once loaded (see [2]).

I am using several addons [5], but the only extra parts used on the ship are some smkoke industries moving parts.

I would appreciate it if someone could help, my Duna kolonization program is totally suck!

What would be a good way to debug what's going on? Are there any in-game logs I can enable, or a console-based method to figure out what's braking my krane?

Did you use tweakscale on the root part?
