Previously it would fail with:
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'bonsai\\bim\\data\\cache\\988c190483ae6bab7cf6b00cee78694d.h5'
Noticed that added drawing camera was linked to the scene collection and after collector.assign it was linked to the 2 collections instead of just 1 - it's own drawing collection and the scene collection.
