well I am gonna try and mail the admin of BT about Floodgate and the other 2 maps.
(River Village and Refinery) - Haven't tried Oldtown yet but i think it's fine
This doesn't seem to be an assist problem.Strange that the other 285 maps work
Their names don't look any different
They all start with MP_
These are the 285 maps that exist in Battletracker:
Canyon
District
River VillageRummage
SF FloodgateSF Hospital SE (noone seems to play that anymore)
SF Oldtown (haven't tried it yet)
SF RefinerySteamroller
Interdiction
Lord-of-War
