Hi Tonymerguez,
Thank you for answering my questions and for sharing those extra details, I shall pass them onto the team.
Regarding not getting the rewards from the bosses. The team are working to fix this issue asap and in case you have not seen it already, more info can be found here: [Known Issue][PS4/XB1] Crafting Menu Reset / Story Items Locked
Regarding the issue where you are kicked, can you confirm for me what region you are playing on in multiplayer? If you’re using Auto, please try changing it to a specific region, and if you’re using a specific region, please try changing it to Auto or changing it to another region further away from your location.
Does anything else occur in your save that would indicate no longer syncing with your friend when they host the game? Such as seeing different items on the ground, or not being able to see items when the other is building?
Have you been kicked out of the game in any other situations?
Do you have a save file where you are the host and your friend joins you? If so, are they ever kicked from gameplay?
Thank you for all the information you’ve shared so far. It may be a long shot, but you could both try clearing the cache of your console by shutting down and unplugging for 2 mins before rebooting to see if that helps at all.
Similarly, though it is again a long shot, if one of you is using a wired connection and the other is using wireless, please try both using a wireless connection or both using a wired connection - this is likely not the issue but another report reminding me of this occurring for someone when they were in the same household. Though you are not in the same household, there is no harm in trying, I think.
Thank you again.
