Ship/subassembly loading UI completely blank after saving very large ship

[foamyesque]

So for reasons probably best left un-examined, I'm building a ship with a very large part count. The save file, which still exists, is 7.7MB. However, if it (or a significant portion of it, which I tried saving as a subassembly, at 7.6MB) is in a save list, that list becomes blank (or in the case of the subassembly fails to load at all).

Subassembly: https://www.dropbox.com/s/c0voq7r8r27kubz/Eve lower stage.craft?dl=0

 

Any suggestions, aside from "don't build that big"?

EDIT:

 

In fact, the SPH GUI for assembly is borked as well; changing the function filter category from pod to something else, for example, produces no result.
