If you join someone else game , The game crashes to the menu. I have reported a video of the bug. It can crash when you first cast or any other cast.
We are looking into the crashes guys- we apologise for this. In the meantime, please check your internet, reset your router and try hard- resetting your PS4.
Still crashes. It seems for me its just this one lake. And its always while casting. Hope that helps you recreate the crash, also you need to not be the host.
Thankyou, this does help us narrow things down a bit- we apologise that the crash still occurs, the devs are looking into it presently!
