[MapProxy] Unusual behavior with configuration symbol names and scrambled tiles?

Hello Bruce,

it's not related to MapProxy but to your client.
Try to add "?origin=nw" after "z/x/y.png". EPSG 3857 and 900913 are not 
the same because handling of aligment differs. If you know the alignment 
of your SRS than add it manually after the URL.

Bye, Mathias
