Same thing again. This time mustang valley ranch. Here is a summary how it works.
I had already uninstalled the map when I noticed this.
I uninstalled it again.
When I get back to the modhub page it was gone.
Then I get back to the main menu.
And when I get into the mudhob again... viola. It was there. Popped back up on its own.
Whatever I did I just couldn't made it go away.
This time my network was clear. No downloads no nothing.
But I noticed that your servers were quite slow because I tired to update the map. Download speed was painful. Btw, the first time I installed this map it was already the updated version. After I uninstalled it, the map came back on its own as it needed to be updated. That is odd.
I hope those data would help you to identify the problem.
Edit: and when the update is over it re-required the update again!!! I didn't even left the update page. It was just there requesting to be updated even after the update was over...
