This may not be a bug, or the item may have been taken (*looks at other Wayfarers suspiciously*), but Iridni left five potions in the locked Lodge for another Kin to pick up. They were crafted potions if that makes a difference.
When the other Kin arrived, the potions were gone. Generally, items not put in the trash don't seem to disappear from an area on reset (e.g., posters). Or so I thought.
The server did not reset in the meantime, but the area might have.
Thanks for any clarification whether this is to be expected and why the potions behaved differently than what I'm used to--such as because of the area they were left in, that they were crafted gear, etc.
