So, earlier today the NUC with the grid reset itself. I discovered that this was due to a Windows Upgrade setting (which I've now corrected). However, I was working in the grid when that happened and lost all the walls in this deck, plus anything that was linked to them (like some of the flooring)!
Couldn't find this in either the trash, or Lost and Found, so I've just spent some time rebuilding the walls and doors. Not finished this yet, but one thing that will come out of this is that all the heights will match! GAH.
