I think I logged this before, but it was probably in a long list of things, so it may have gotten lost.

Add an object to a plan for C/2007 N3 Lulin. Give it the ID "C/2007 N3" (with a space between the 7 and the N), and the name "Lulin".

Add an observation and a user image. Note that you don't get an image icon in the Objects list.

Change the name to "C/2007N3" (delete the space).

Now you get an image icon.

Switch to Observations tab.

While the list says it still has 1 observation, you don't see it listed in the Observations list. If you put the space back in the name, your observations come back but your image is gone again.

Fixed. Cannot reproduce the image problem, but removing the blank from the ID no longer "loses" the observations made on the object.
