"Road connection between the cities of Kazan (SibirMap 2.6.1) and Kirov (ROS13). <-----
There are no fireworks (as there are with me) but it is practical.
I must mention that the height of the roads between the two projects is about 160 metres, so it is what it is.
It requires: All DLC maps, RusMap 2.4.8, ROS 13 and SibirMap 2.6.1.
The connection is compatible, but removes new areas from the latest version of SibirMap 2.7.0. (Kazan city area)
It does not work with the Kirov map!!! "
Look here for a tested loadorder by GMC :
