We have a report, replicated by a moderator, that right-clicking an item into a buying chestshop pays out the price but does not take the item from their inventory.

HyperConomy v0.974.4

This doesn't happen for me on my test server. What item are you using? Or is it an enchantment? Any details on how to reproduce it would be helpful.

Sorry, I don't have the details. I'll check with the mod who reported it

There have been a huge number of code changes so I'm not sure this is still relevant. Feel free to create a new ticket if you're still having issues. I should get to things faster now that all of the tickets are in one place.
