My son and I have been playing in a shared world since Grounded 2 came out. Last we played together was the toxic tangle update where we played thru all the content/etc. I played a little bit more without him to gather materials/build base/etc.(which I've done every update so far). Now with beat the heat out we finally found time today to try it together, I login to shared world no problem. When he logs in he has nothing and is at the start like a brand new character. I've tried loading backups from the shared saved. I've tried loading Non-shared multi player standard copies of the world I'll make every so often. No matter what, he always joins in with nothing. He is using same Xbox account to login, but its like whatever Xbox ID to player link inside the save file got lost. Is there anyway to edit the save file to relink it? How do I fix? Suggestions please.
