OpenRA

All the maps need an upgrade or something? In RA map menu I only see "official maps" and I don´t know why

You will need the new revision of probably all you custom maps. In the recent playtest, the mapformat has changed from version 7 to 11. Go fetch your custom maps from the resource center.

We now also version the maps directory, you need to put the maps into "maps\<mod>\<version>" e.g. "maps\ra\playtest-20160403" in your support directory.
