In 0.15.10, I could zoom into the map to make it show the 'world view' where I could see other players doing things etc. Since 0.15.11 I can no longer do this at all, instead it just reaches a maximum zoom level and shows the solid-coloured map. Other players on the server can still do this. I have radars in the area, so that's not the problem.

This is the furthest I can zoom in.
