I have a big problem in the coop, 3 times  the monster hangs while playing in the war zone, the monster have 61 life points and can not be killed (perhaps when using the jump skill with two-handed axes and hammers). 

Besides, there is no additive dlc, you can not reach the max level of morality or maybe I do not know about something, I have level 65. 

Game crunches terribly with one player in coop.

There are problems with sound, I do not know if it's twitch tv's fault, when I started using it something started to happen.

 There was also an application error sent to Sony.

Problem with searching for players, sometimes the window does not appear.

The app hangs sometimes.

Edit:
I forgot to say about the initiation (reset and reinstalling the ps4 system), I did it last week, perhaps, before installing Martyl. I am now reinstalling the game because I have system errors.

I do not think you need to do this every 3 weeks ...
