Craft in save unusable to Spawn

[Nerfclasher]

There has been some reports including me that has this problem including some other people all you have to do to replicate is see if any craft in your save file but check if it's using the KerbalX mod that causes the problem because so far I could guess that

I use KerbalX all the time and have never seen any issues. Unless there is a way to replicate consistently there is not much I can do about rumors.

It mainly has to deal with crafts that you make yourself that are in your save which cannot be spawned by vessel mover

I have encountered this before ... it is the save file that has been borked

If you are unable to do away with your save file that is doing this then a workaround is to copy the craft file that you want to spawn to the stock ships SPH folder

Also understand that the spawn vessel function is technically still experimental and is known to have a few gremlins
