a) A sourceFile has an object with UV mapping.
b) A destination file contains instances of the sourceFile (linked, reference)
c) Inside the destination file → double click any block → wait for the source file to load, rotate the UV map in the source file → save → close
d) You end-up back in the destination file, but the block instances did not update their UV mappings.
(The destination file needs to close and reopen for changes to take effect ?)
