As the title says, we've observed a horrible bug in which, if you have belongings in that market box and let someone else rent it, all items can vanish from the box, including the 'loot all' button.
We experienced this on Grunskogal Skovald (Pool) and Dagna Alestorm (SovietGrowlithe).
When did this happen? There was a short period where this bug was introduced last week, and we quickly fixed it the same day.
On the 25th of this month. Around noon on Pacific Standard.
