I cant connect to the server of my friend

Cant get into the game as it keeps crashing no idea if this because the mod is out of date now or there is something wrong.

Ran fine while playing, but saving was pointless because the game crashes to desktop upon trying to load any save on this map.

I found a few bits of impassable terrain between the east and west halves of the map which basically meant that you could only traverse the two sides to the south. I'd consider these bugs as by appearance the tiles should be passable, and the units try to path through the impassable areas which ultimately just cancels their actions instead of going around.

The first was near the north coast, west from the western-most ally and south from a wyvern tile, there is a swamp tile that connects to a tile to the east but not passable.
The second was a little to the south of this, pretty central in general, south west from the skyrmir and at the north of the big stone wall running north-to-south. There is a stone path going over the river north-south which connects two tiles but is ultimately not passable.
