Happend to me about 10 times so far. Multi-player is loading on PS3, orange bar goes all the way over and then stops with the words 'awaiting textures'. Played on the maps before - just happens 1 in 10 times I reckon...
Alot of ps3 and xbox360 users are experiencing the same problem. I even am. Hopefully they will soon fix the issue.
It's happened to me twice, both times on the initial load of Nuketown 2025. Once I think the bar was all the way across when I noticed the message, the other time it was only halfway.
