PS4 version crashes and lags a lot in Survival Mode

The games lags and stutters in solo survival mode and it seems to get worse the farer I come into the run. It feels like very hard online lag which makes no sense in such a solo mode (I am in Germany by the way).
Also it crashes several times a day, especially when Lum is involved, see here:

Love the game to death since I picked it up this week, though :slight_smile:
