Disgaea 3: Absence of Justice [BLUS30181]

Alright, so I consistently get a freeze after around 23 minutes of being loaded into the map Chapter 4 - Psycho Room. I don't even have to do anything, just load the map and leave the game running and after about 20 minutes or so the game freezes. I tried to see if I could get it to happen in the hub world but after 40 minutes I was fine, so I'm assuming it's this map. I'll try loading another map and see if  I can get a freeze there as well.

Edit: I was able to go 1 hour and 17 minutes without freezing in the map Chapter 4 - Murderous Intent. As a side note, I've also had the game freeze in a cutscene at least once but that's not as easy to replicate. I think it was the intro cutscene to Psycho Room after just having completed Murderous Intent.

Edit2: I downgraded to rpcs3-v0.0.9-10159 and have had the map up for about an hour now with no freeze.

I think you don't have to downgrade that much, I'm currently in 0.0.10 - 10596 version and it runs fine, I don't know at which point on the 0.0.11 versions this game started to suffer but at least on the 10's it seems to run fine.
