Same here, after the last update 1.05 game is crashing an alarming rate. This is very critical!
We cannot give some info about it, because is hard to reproduce... it happens randomly... like engaging zombies or players, walking or running around.

I will do some cleaning on my storage and post here if helps a little bit.

@twgolf66 What do u mean delete all the game history/data ?
Reinstall the game ?

This is very critical for the game, because the core of gameplay is engage enemies and zombies, if you can do this due to possible game crashing, its not worth playing.

Yes, after the last update I get blue screen (PS Error Report) every 30min.
It happens randomly, like walking in forest or engaging zombies and players, changing servers.
I'm sending the bug report to Playstation after the blue screen happen I dont know with help you guys see the logs of the crash.
