Here is the url for the steam page regarding the latest patch for anyone interested:

I have seen a few posts on here where people have been having problems related to selling too many items to merchants (over time) causing some kind of error with loading the game. This seems to be addressed in the patch.

I would still very much like to see a list of changes specifically addressing the platform I play on (PS4) please.
