The gamemode no longer ships with any maps by default. It was a nice thing back when we had only 2 or 3 maps but now that we have almost 20, this is serving to bloat the addon.

You can still subscribe to a seperate addon for the maps here: http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=244859331

Servers will now need to download the maps and setup fastdl -OR- servers can make clients download the mappack workshop addon by adding this line to their server.cfg:
eft_downloadmapaddon "1"
Note that this does not install the maps on the server, rather it allows the server to not need a fastdl.
