To those wanting use a RWG map - I strongly recommend generating it on your client (Single player) game.
Then upload it to the server using ftp.
Trying to get the server to generate an RWG is messy....
With map generators like Kinggen (and Nitrogen of old) The Funpimps really should have a better RWG solution in place......
I generated an RWG map using 7DTD as Kinggen is (or was - havent checked to see if it is A20 compatible in the last 24hours) and it took 10mins for an 8k map. Kingen does it in under 2 mins with soooo many more options..
