I am the author of a small addon called Aardvark; the addon will auto destroy listed items when a vendor window is opened.
Since 90002 when I visit a vendor the destroy item messages print but the items themselves are not deleted; no matter how many times I close and reopen the vendor window the messages print about the items never leave my bags.
I can run the destroy function manually after I have already opened the vendor window and then the items are destroyed.
This is the error I get;
1x [ADDON_ACTION_BLOCKED] AddOn 'Aardvark' tried to call the protected function'UNKNOWN()'.
