Post-GU11, I crash/lock-up whenever I switch to squad screen. At least one other person in my outfit is having the same problem. I'd like to check the new squad screen out, but that's not likely to happen right now...
yeah others have the same problem too... and more bugs are there, see here: https://forums.station.sony.com/ps2/index.php?threads/unable-to-open-social-tab.135565/#post-1882910
