Like it says. 
Good to know. I’ll have it updated!
But, do we have anything in the game linking to img.wolfery.com? That is more or less just a simple folder where I sometimes upload images instead of using imgur or other services.
This was more flailing, I’m afraid. Before you helped me find the proper landing page, I found the mockup image first. 
I see! Yeah. I would be surprised if the game would have any reference to img.wolfery.com as the game images are found under file.wolfery.com instead . Or directly under the client at wolfery.com/img/
But still good to know! And good to getit fixed.
