Now, I'm newly-returned to the game, and I'm having issues which had previously been fixed in Space Marine when I was originally playing the game.

When the game was new, a "Migrating Host..." message would mean time to panic, because it frequently resulted in the game freezing. They patched it, and that was one of the things that was fixed.
When the game was new, joining a match was often worrying, because the game would freeze sometimes. They patched it, and this was also fixed.

Now, I've come back to the game, and the same problems are back, and rather brutally so.

I'm just wondering if anyone who's been continuously active on PS3 has noticed, and if it's related to something changing in the game, or if it's more likely to be a problem with the latest PS3 update, which has caused similar problems for a few other games I know of.
