Description:
For those wishing to use RusMap 1.8.1 with the new Baltic DLC can now do so. There is a fix:

Replace the RusMap Def and Map files with the two in the unofficial package. What it does is to remove the conflicting and overlapping areas of RusMap and allowing it to load. be aware though that at the moment there is no direct road connections from RusMap to the St Petersburg and Baltic areas. There is however still a road connection between Warsaw and Brest. Also road connections restored for Southern region and The Grear Steppe.

Suggest you backup existing Def and Map files, particularly if you want to go back to your ProMods map.
