Suddenly older offline maps don't work any more

[Alexandra]

Hi,
I'm using Locus Map since almost 10 years. Currently I have a Samsung Galaxy S24+ with Android version 16. Locus Map version 4.32.2.

I have many offline maps downloaded during the past years, e.g. France (north) LoMaps 2017.03.14, France (south) LoMaps 2018.05.22, Switzerland - Lo Maps 2017.07.22, Austria - LoMaps 2017.06.09, Luxembourg - LoMaps 1018.08.11, Belgium - LoMaps 2018.08.11, Netherlands - LoMaps 2018.08.11, Czech republic - LoMaps 2025.12.06, England - LoMaps 2025.12.06, Scotland - LoMaps 2023.09.05, and many more.

I'm living in the area of Germany South. Today I noticed that the whole Germany South area was grey - showing no map. At some zoom level at least some city names were displayed. Then I have deleted my offline versions for Germany North and South and have downloaded my old versions from 2017 again. Germany South remained grey and in Germany North at different zoom levels the map tiles don't fit together any more. Then I have deleted this again and have bought and downloaded the newest versions of the Germany (north) - LoMaps 2025.12.06 and Germany (south) - LoMaps 2025.12.06. This is working fine.

My newer existing maps for Czech republic, Scotland, and England still are ok. Also the borders between the newer maps are shown correctly, when I move from one country to the other.
But all older maps from 2017 and 2018 are not working any more. The tiles do not fit together and for example cities of Italy are shown mixed with France. Also the new German map is not working correctly, when I move to the border near a country for which I have an older map. Then I also get a mix of tiles.

Do I have to delete all my older maps and to buy never versions?
Or is there a chance to fix this?

Thanks and regards,
Alexandra

Same here, using locus since 7 years. I also see "strange" images. Just random tiles, streets, ways, rivers, contour lines, ... stand and end on the borders of these tiles. Currently, Locus is impossible to use for me. I hope, I'll get an answer (even better, a fix) for this problem soon.

This image shows a small portion of the Italy North map. It's totally unusable (as anybody can see easily)


It appears for example with Austria, date March 27th 2022, also with Italy North, August 15th 2022, Germany south, June 11th 2024. Locus Map version 4.32.2

My phone is a POCCO X6 Pro 5G, Hyper OS 2.0.209.0.VNLEUXM, Android 15 AP3A.240905.015.A2, security update 2025-11-01

I have just deleted my Austria map and downloaded it again: Exactly the same result. It seems to be a bug in the software. I am waiting for a fix.

Hi guys,

thanks for the bug report, and sorry for these complications.

Firstly > are you using our internal themes? Just open the left side "Map-screen content" panel and under the selected map, confirm you are using one of our internal LoMaps themes.

There should be a problem with mixing very old maps (version 3, 5+ years old) and the new V4 maps. Really, the best solution is to update the maps.

Anyway, if you confirm, you use one of these themes and still problems appear, I'll try to look if there is something I may do with it, not to force you update the maps.
