there is 3 of us that were playing together when this happened.

We walked past Lopatino up the map, past the bus stop place to the left..over the train line to the top left most town with no name.
Then we kept on walking up the dirt road to the last blue dot on that map until we hit "end of the world" where theres a clear line of forest and just generic land.
From there we took a left and follow "end of the world" line until we hit the road that curves off the map. we took a right on the right because we noticed there was more land out that way that was never there before.

Thinking this was opened up for future towns we thought we would follow it south (keeping the bushy ling to our left) and thinking we would just end up at kamenka.

After a real long time of walking we notice a train station and find ourselves at Gvozdno.

Some how ( all 3 of us) were on the other side of the map. we were definitely off the map west of lopatino and we didint take any rights so its not like we loops up around the top of the map, and we didnt go through the middle of the map as we would of seen all of the towns and we were north not south of the train station near Gvozdno.

Are we going crazy?
