Got the same issue. Same procedure, same outcome. Save works in singleplayer, even for a friend, so it's definitely server side.
Not a good sign that there are no answers maybe we just have to choose a different server host, sadly.
Hi lads!
I am having issues uploading a world I created with worldpainter (that works in singleplayer) to the server.
Did anyone have the same issue and knows a solution to that?
Thank you so much in advance!
