RapidWeaver 8.1 (20579) - Can't Save or Export

I just updated to 8.1 and was working with my site now I can’t save my updated project file, nor can I publish - just spins out waiting to “export.”

Not a terribly complex project file (using Mac OS X (High Sierra with current patches), current stacks installed on RW app). I was able to export the site but I can’t save it so I haven’t closed it because I don’t want to lose the work. Thoughts?

Do you use any plugins besides from stacks?

Can you do a ‘save as’?

If you don’t have one, make a backup of this file.
I would send the file to Realmac support.

Question: when you choose Save or Save As from the File menu, what happens? Does it give you an error message?
