Frequent Game Freezing on PS4 Local Play

Hi there.

Over the last couple of days I have experienced complete game freezing during playing. Issue experienced at least twice per day. Today it has happened more frequently, thus the reporting of bug today.

When the game freezes, it does not crash or exit to the playstation OS. No error messages received. It just freezes in place and loops whatever sounds were playing in-game at the point of crash.
I can return to the PS4 menu by pressing the Playstation button. I need to kill the application and launch it again.

I am also noticing some gameplay slowdown (slow frame-rates) before the crash when there are numerous enemies onscreen and or in the vicinity just offscreen. Unsure if related.

Also, each time a crash has occurred it has been while performing bounties. (Wizard - Seasonal Character) Experienced freezes in multiple Acts.
