Thank you for such a quick fix, that's great!
I was wondering about the windows "move with host" issue. I cannot test because I cannot install from daily ppa (I'm on KDE Neon, there's some qt libs issue, so I use AppImage) It gets maybe even more complicated now, but if I got it right, all boils down to this:
window copies the PLACEMENT of his host wall.
-If the base sketch is moved, wall's PLACEMENT = 0. So, the wall moves, but the window copies "0".
-If the window is manually (with the MOVE tool) moved with the wall, it gets it's own PLACEMENT while the wall's PLACEMENT is still 0, so they mismatch.
My solution was to "move with host = false" and then simply select everything I want to move without relying on automation, and it works.
Now, could it be possible to make window actually track the BASE SKETCH PLACEMENT + WALL PLACEMENT of its host wall? Can a window "see" the base sketch of it's host?
Sorry if I'm just wasting everybody's time
