you have to do 1 of these things, you can check what feels best for you
1) pick a otm from the xvm setup,
2) disable contours
3) remove the battleVehicleMarkersApp.swf file manually each time you update the modpack (located at Tanki\res_mods\1.20.0.1\gui\flash\battleVehicleMarkersApp.swf)
lesta and WG have different game files, which complicate things fast
