Game has a huge bug right now in 1.0 on consoles which decreases the spawn of fish and materials to 10%.
But PS4 players are also reporting to have it, so not sure if it's only Xbox right now.
Developer:
Hey everyone. We're aware of this issue - it's affecting some Xbox users (not PS4 or PC). We're putting together a patch to fix the problem and submitting to Microsoft today. Hopefully it wont take long to get it out there. Sorry for this - it's our first console release and we're doing our best to address issues that are coming up as quick as we can.
