You are correct on the steps order. (I just launched the vessel and immediatly reverted to SPH). Can you tell me more about what is invalid in my vessel ? The vessel was a fresh new one. Only using stock parts. I can reproduce it with every vessel I have in SPH/VAB. I created a new career and I could not reproduce it with a fresh new vessel. Could be my savefile somehow ?

Hello, I suspect there is a problem with this mod. I don't know since when it happens because I didn't play for a while. Also I don't use it because I didn't created a new career after release of CommNet (introduced in ksp1.2) So after reverting to sph/vab, I'm stuck in the vab/sph. Here is the log output : [snip] Exceptions starts on line 20852 when initializing editor mode.
