A "network error" kicked me from my 25th ranked match as Alice I believe, so when I booted up the game again my stats said 25 ranked matches played, but Bombardier (Play 25 Ranked Matches with Alice.) didn't pop/unlock. I've since played a few more ranked matches with Alice, but no change.
If I can't hit the "trigger" for 25 plays again, my Platinum is unobtainable it seems. Not to mention I can't earn single player trophies since the "network error" prevents the mode from even starting. This is a huge shame, since Sony is now offering tangible rewards for earning trophies.
Shame no more!
I can play "offline" in solo mode now, and the Bombardier trophy popped at around 30 matches with Alice. The latest patch is like Christmas morning, hooray!
