The Cities did not generate, but after I removed only this mod the Generation worked perfectly.

I will add it to the mod testing just need to know in which version you try it

@CreepyChicken I just got the same result as you.
If you want to see the results look up here: https://trello.com/b/xTk6aSYa
You can close the Issue now if you want.

What is broken here? I installed the Lost Cities and enabled it in advanced world options and well...

@jediminer543 thats interesting on my server I couldnt get it to run maybe I am dumb...

@jediminer543 Okay Its just a bit tricky to set up on the server side but it works fine now
