I just opened a file on one computer in Glyphs 1153 and found that the Smart Component Settings are gone. Yesterday I was working in a 1150, and if I open the same file in this version, those are fine.
That’s really scary, because I don’t know what else happened to the drawings 
Works for me. Can you send me the file?
Solved:
The issue was, that I clicked on »Show in Tab« in the component-have-moved-notification, which made Glyphs to activate/present old Layers instead of the (by me expected) recent master layers. In those the settings weren’t set up yet, and hence my shock to be confronted with false drawings.
Sorry for this!
