@OIF1ADVET - sorry for the delay in getting back to you on this. Thank you for the extra confirmation and those additional details. I’ve created a unique report on your experience for the team to look into. As this has happened more than once for your current save, if it is still playable using your workarounds would it be possible for the team to get a copy of it? I feel like this may help them investigate other triggers. If you’re happy to share your save, the instructions can be found here: [Save File Request]
With regards to leaving the wildlife on passive, I too am wondering if this would prevent a freeze or if it’s the changing of the setting rather than the setting itself that’s having an impact. But I’m not a dev so I’ll leave it up to them to figure out this mystery! If you do try other methods though, please let me know and I’ll update the report on this - as always your information has been very helpful. Thank you 
@Don802117 - I’m sorry to hear this affected your save too. Had you just traveled to a new island or lost anything through the ground / in the ocean? If you do try OIF1ADVET’s workaround, please let me know if it works for you.
@quintennyson - Thank you for reporting these details. Generally the items in the toolbelt relate to the inventory and toolbelt wipe issue. Did you experience both this and a hang in the “Cleaning Up” phase in the same save and around the same time?
@josh - to follow up with this, I have discussed it with the team and have submitted a full report so they can investigate it. If you haven’t started a new save in the same slot yet, does the data for the original save still exist on your console even if the game cannot access it? Please also confirm for me if you see a “Continue” option or just “New Game” when you load in.
