It's a simple fix indeed.

It has already been updated for 3.0.

I haven't forgotten about the issue.

Of course you can, a comment can include any text you want.

I just use my addon, BananaDKP, it takes care of everything I need. But of course we use our own custom DKP system that is far from what you want.

Actually I removed the FuBar plugin at a later point. There's only LDB support now.
Although I could maybe add it back in.

I just tried using SBC here, and everything works perfectly.

Right, then ErrorMonster won't be able to intercept it the way it's made now, and it won't have intercepted it previously either, this is not a regression or a bug.

Should be fixed now, thanks.

That means the "Quest Completed" message is added to the UIErrorsFrame in some non-standard way, or it might in fact be an addon printing it.

Does the default UI show that message? I don't think it does.

I'm not quite sure what you mean, it already scans your focus target.

Hmm perhaps you could add this line after line 32 in ErrorMonster.lua:

ChatFrame1:AddMessage(tostring(event) .. ": " .. tostring(message))

And then when you get a new Quest Complete message, tell me what the line in your chat says (part before the ':').

No. All system messages that WoW would direct at the UIErrorsFrame, not the ones shown in the ChatFrames.
