Circular imports

If I try

from rapthor.lib.observation import Observation

I am greeted by

ImportError: cannot import name 'Observation' from partially initialized module 'rapthor.lib.observation' (most likely due to a circular import)

I see that rapthor/lib/observation.py indeed imports rapthor.lib.miscellaneous which in turn tries to import rapthor.lib.observation, so it does look like a circular import. First importing rapthor.lib.miscellaneous before rapthor.lib.observation works around it, but this looks like a bug?
