Thank you for the very helpful advice! I won't be able to change this version of the map/scenario any more, but I have a half-finished version 3 in my CIM on which I'll try to include those folder/name changes before the upload... hopeing that the uploader will still accept them then. Will still be a little while until v3 is ready though.

The comment section here should also help : https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=198567683
Also, you need to rename it Usti_nad_laben2

i have found a solution. but this site is in german.
Maybe it helps, when you use a translator.
You have to move the map of this scenario in another directory. And that works :)

Hi, I'm very sorry for the troubles the scenario seems to be causing. Sadly I have no idea what to do about that, here in my game it works fine. If anybody has any idea where I could start to look for a solution, please do let me know. I'm completely stumped.

i have the same problem. what can i do?

Hi, if I start map in Sandbox-mode, it's perfect. But when I start it in scenario first time I got an empty map. Since the second try I got a map with landscape, but without streets, buildings and hunans, so without the city... I have downloades all three files. Can you help me?

Hi, Do you have downloaded all three files (map, scenario and rule set) from the collection? If you have, what exactly doesn't work with the scenario or what happens when you try to start it?

Great map. Works on its own BUT the scenario does not. There must be something you or the subscriber can do.
