Yes, the Omaha in the Map pack is busted and we are no longer using it. If you get the new Omaha, you must delete the old one before you install it.
Also, we are considering putting together a better mappack so peeps do not have to go all over the place looking and downloading new maps. We have just set up another testing server to test new maps before we put them on our main custom map server. hopefullly we can also make it self installing. We know its a total pain in the ass to have to download new maps all the time, but the new maps seem to be coming out every other day - some are pretty good too. We just want to make it easier for the public to enjoy NAW in all its glory.
This is the Omaha you need: Omaha beach 1[1].22
