In PlanetSide 1, I have been trying to enter the caves. I have played PlanetSide 1 for a very long time (and am a Markov Vet) and have never had this issue until recently. When attempting to enter the caves, it says that I do not have CORE COMBAT expansion pack and cannot enter. However, when I look on the map, I can see others are getting in because the bases are all mixed up, but I cannot. When I see others online, I ask them if they can get in, and thus far none have said that they can. I am extremely annoyed by this, and want to just play in the caves a bit. Does anyone have an idea why we cannot get into the caves?
