Hi @MrWillis89, welcome to the forums,
I moved your post to its own topic so I could address it directly rather than potential confusion in the comments section of the other post.
I am sorry to hear you’re experiencing issues within multiplayer on Xbox. I’ve responded to each of the issues you mentioned below. If I happen to have missed anything, please let me know.
Story items locked in crafting menu:
As you may have seen from other posts, this is an issue the team are aware of and have created a fix for. They are currently in the process of testing it and getting it ready for release in an update. In case you have not seen it yet the latest info on the upcoming update is here - Message from the Team - Console Update Progress Info - But we do not yet have a set release date for this yet.
Crates issues
Issues with crates, both desyncs with player 2 not being able to see items inside them, and items appearing outside of the crates, among others are in the top priority list for the team. From what I can see in the reports, the team are continuing to work on a fix for these issues. Unfortunately the current known workaround for this issue is as you described, the host must remove all items and replace them in order for Player 2 to see them. Understandably this is not ideal and can be very time consuming in a gameplay session for players.
When you say “All of our crates were glitched” are you referring to them having items floating outside them or they had moved position in container shelves you had them stored in?
Slow FPS
Did your friend notice your character moving strangely at all during this time?
When it occurred, were you crossing the midpoint between two islands or did it occur closer to an island?
Can you confirm for me what the NAT type in the network settings on your consoles is set to and what region you are using to play?
Are you in the same household with the same internet connection or a separate one?
Regarding hosting the same game - the game save is maintained on the hosts console and every save saves to their storage. You would need to start a new save to host a game yourself, you can however ensure you have the same map if you copy the seed number of the hosts game.
Thank you for your feedback and I completely understand you not wishing to continue playing with the issues you have described above affecting your gameplay. While a number of them are issues the team is currently working on, any extra information you can provide about the game setup and your experience with the drop in FPS would be greatly appreciated.
Thank you.
