Caltopo mbtiles maps no longer working

[jmnorvell]

Since about February of 2020, mbtiles maps I make with the Caltopo site don't work in Orux. The behavior is very strange. When I first load the map, it seems to locate it 3,700 miles away. With GPS on, it will time out and return to my current location, but immediately ask to load another map, and the map in question is not on the list. With "switch map here," it does not show up in the list. I have made many test maps now, with 15 and 16 as the highest zoom level. None work.

The Caltopo interface says Garmin mbtiles. These map works flawlessly for years. Any idea what might have changed? (I've posted to the Caltopo help forum as well.)

TIA for any help.
