He's not the only one with this problem. I uninstalled both sins and the expansion and reinstalled them and ran into this trouble. All of the icons in the research screens for the new stuff are wrong or missing. In the rest of the HUD new (expansion) vehicles don't show up though they are visible once you zoom in.
I'm having the exact same problem. I've gone from being able to play a game I enjoyed [sins] to not being able to play a game I was testing out [entrenchment]

I'm having the same problem. I downloaded entrenchment today (Jan. 31) and while the beta is interesting I can't play regular sins against other players anymore.
I have to agree with all the other posters. Since the Jan. 27 update the game is virtually unplayable in mp. Please fix this as continuing problems like this make it less and less likely people will continue to play or recommend the game to others or buy your microexpansions.
