Can't save sub'assembly when shift clicking

[Rockyfelle185]

For a long time, since they were introduced, I've never gotten the point of using sub-assmbly's, the reason for this being you just can't save what you want to save, unless you happen to have one side avaliable on the pod, which you very well may not have.

However today when I accidentally dragged a norma part into the sub-assmbly saving area, it said that it could save fine, so obviously there shouldn't be an issue with saving any craft.

I proceeded with trying to grab the same part again (with one of it's attachable sides completely free), using shift+click, and then s expected, it did not work, but why? This should be possible, the logic of the system itself says this should be possible, and the system is for many people useless without this feature.

tl;dr you can't save attachable parts because they aren't "attachable", not sure if this is a bug since it's allways been like this as far as I hope, but I sure hope it is, and that it will be fixed.

Update: This is only appears to happen when a pod(or first placed part?) is one of the parts connected to the selected part and does not have a free side, in other words a solution to his (hopefully bug) is to save the part of the craft above the pod, and under the pod, since you can't save the craft if the pod is in the middle.

You cannot make an entire vessel into a sub assembly, sorry, sub assemblies are by their nature sub sections of the vessel, this is by design.

If you would like to load a vessel alongside another vessel you should use the "Merge" button in the vessel load dialogue.
