Display problem of IGN maps on map overlays

Hello Locus map team,

I have this problem for a long time, but only now I make this report.

I have French IGN maps, online and some offline areas.

I have very often problem when I want to display it on map overlays. To see the screencopy of the error. This hapen in both IGN maps online and offline.

I found a turnaround : I select IGN map as base map, use it a little bit, select offline LoMap as base map and then IGN map works on map overlays

Note:

- I always use offline LoMaps. Very few online maps.

- Offline IGN maps are downloaded at zoom level 16 only.
