maybe a silly idea ... but is it that hard to create a bat(ch) file that swaps all the maps available in the map folder ever soandso minutes
okok ill explain
2000+ files in a map ... batch creates temporary folder
fitrst 200 stay .. rest gets moved
after 30 minutes the 2nd 200 get moved back and the first 200 go to the temp ... etcetcetcetc ...
it isnt pretty .. but its a real easy workaround while waiting for the updated server
