Bidder is broken with the latest WoW patch. The lua error prevents quitting or logging out of the game unless Bidder is turned off in game and a reloadui is done first.
["message"] = "Error: AddOn Bidder attempted to call a forbidden function (orig()) from a tainted execution path.",
["count"] = 3,
["context"] = "AddOn: Bidder",
["stack"] = "[C]: in function `orig'\n...rface\\AddOns\\Bidder\\Libs\\AceComm-2.0\\AceComm-2.0.lua:2072: in function <...rface\\AddOns\\Bidder\\Libs\\AceComm-2.0\\AceComm-2.0.lua:2066>\n(tail call): ?\n(tail call): ?\n[string \"*:OnClick\"]:2: in function <[string \"*:OnClick\"]:1>\n",
I've updated all the addons. The error code you reported was a result of Blizzard changing the ways addons can interact with the logout event. I believe I've fixed it, but can't be sure I've tested every possible use case. Blizzard also changed the way addons can trigger sounds, so I updated all the sounds. If you notice anything breaking, please let us know!
I've got the new raid added in and will be updating that for boss tracking as needed.
