thank you for your fast answer. I understand.
Unfortunatly it´s not possible to combine a winter theme and a summer theme within one XML using Locus style parameter if you use different colors for backgroud and nosea
Background ist set to light green/brown in right picture
With Locus maps it looks like this
Locus maps: left winter theme right summer (hiking)
OA maps: left winter theme right summer (hiking)
But it seems, that there is another bug, can you please have a look? (at the coordinates)
I use still the light green background, are the tiles damaged?
