I tried the keys ring for a couple of times, and it happened that all the keys I put in it disappear for no reason...

Does it need to stay in my personnal inventory ? Because sometimes I'm leaving it in a chest in the houses I built during my journeys, and when I take it back, the keys ring is empty !

Thanks in advance for the support, the mod is really great !

Any process I can use to duplicate? I can't recreate the issue by simply leaving the keyring in a chest. Are you using the latest beta (0.9)? The keyring had issues prior to this release.

Yeah, I'm using the 0.9 beta.
It's maybe due to an other mod? I'm using a backpack to travel between houses: Wearable Backpacks mod (from curse forge)
So I usually loot several chests around a house, then I pack everything needed for surviving + keys ring and move to another area...

I used Wearable Backpacks but I still can't recreate this issue.

Can't recreate and haven't received any additional feedback.
