Items disappearing from my vendor without being sold

4. Details:

Items have been disappearing from my vendor located in Central Brittany without being sold. I get no notification of sale, no gold deposited into my bank. They are just gone like they were never listed in the first place.

So far I have lost 2 Wooden Storage Chests valued at 1k each, 2 listings for healing potions in stacks of 3, and 2 listings for Recall and Teleport Scrolls in stacks of two.

This has become a HUGE set back! I spent hours gathering the resources and raising my crafting skills in order to make these items. Dumped everything I had into them and was hoping to make it back when they sold, and now I am just screwed.

5. Steps to Repro: List items for sale on my vendor and wait for them to vanish without payment
