XBee3 gives error when entering discovery

After having my Xbee working for a few days I now get these errors when entering mapping mode.
Error discovering neighbors of
Cannot find the local device address.
Remove it from the Radio Modules list on the left and add it again.

This first manifested itself using network assistant when it would fail to draw any connections between devices. I have two separate maps and I would load different config files to toggle between the two and this all seemed to work well until it suddenly stopped.

Any advice would be welcome. At this point I think I have a lemon and I’ll have to send it back.

Sounds like your module left the network for some reason. Try doing an network reset on it. (ATNR0)

Yes, I think that was it. Working now.
