Hello oligan21
Unfortunately, the map cannot be installed. I have been at it for 2 days now and have tried everything, but unfortunately without success.
I am always in the sky
I assume, as @TheFloxiC wrote, my Omsi2 does not recognize the objects because the letters are written in a different way.
ZitatI checked it properly and the problem is following: Your computer cannot read polish characters in the name of the folders (ł Ł). This causing you can see only sky.
