USGS tiles not displaying correctly

SARTopo Offline v3786. Forest service base layers appear to be working correctly, but the USGS layer looks like it's randomly missing tiles. As an example, map.html#ll=36.43117,-105.53004&z=14&b=t is attached. Redownloading the USGS tiles does not fix the issue.

    Looking at this further, I think it's possible the USGS downloaded tiles are simply not working at all, and the tiles I *am* seeing in the offline app are ones downloaded on-the-fly when the network is working.

    I can verify that the file is good. Basic question, but it's moved into the data/tiles directory?

    It is. All of the other downloaded tiles work perfectly - FS2016/2013, all of the other data layers as well. Only having this issue with USGS 7.5.

    Any tips for "fresh installing" SARTopo to make sure I'm working with a clean slate? I've just been deleting the folder containing the "fresh install" stuff, is that enough?

    Topo layers are slightly different than the others, because I wanted the offline version to have one layer that loaded automatically. Just remembered a previous bug related to this, although I thought it was long fixed. In (or for caltopo offline), can you add the line:

    And then restart the app?

    That fixes the issue, USGS tiles load normally now.

    This has been fixed in the codebase, I'll try to get an updated offline version out soon.
