There has been a case on the PS3 version where the game has been freezing, and locking up more than usual since patch 2.1. I have had to cut my game off 6 times due to this issue after the patch. And have had to do it 3 times this morning.

Froze while going to retainer in Lominsa by market boards.
Froze while riding chocobo.
Froze while attempting to zone. When game came back on I was in the area I was originally suppose to go to.

All I can think of at the time, but it has been freezing frequently. Thank you for listening, and other than this I am enjoying the patch.
