For the achievement "The only escape" on Halfus Wyrmbreaker" the addon says "achievement complete" before either of the drakes are killed. I killed the boss because it told me the achievement was complete but I didn't get it. Came back a week later to try again and it's doing the same thing. As soon as I free the drake it says complete but the achieve requires you to kill the drakes within 10 seconds of each other not just free them. Why would it say complete before they're dead?

For the "abuse the ooze" achieve on Sjonnir the ironshaper the tactics note says "wait for the ooze to form into ONE iron sludge. Kill it then kill the boss" but the achievement requires you to kill FIVE iron sludges. If you follow these directions you will fail.

I don't know if is because I already completed the achievements or not but I'm trying to help a friend to complete their achieves for both, Glory of the Legion Hero and Glory of the Argus Raider and every time we meet the achieve the addon gets crazy on both Raid Warning and Chat repeating the same message over an over that we can kill Boss and that I already complete the achieve on 10/11/18. Even after we kill Boss both Chat messages and Raid Warnings don't stop and the only solutions is to reload UI.

Also, I get "There are too many errors in your UI (chat spam)" when that happens. Actually not only when that happens but when IAT is enabled :-(

Last but not least this is an addon I can't live without it :-)

Here is the link for you to download the InstanceAchievementTracker.lua. Let me know when you get it so I can delete the file in WeTransfer.

Hope that helps

So what you're saying is that if I had selected a sound for "play a sound when an achievement is completed" I wouldn't had the issue? Damn, I not even noticed because I had all the options in default and never changed anything really until yesterday when I disabled "Announce Messages to Raid Warning" but the chat message spam issue still happened after we met the achieve.

Anyways, you're very welcome and I'm always glad to help fix or test anything. Feel free to PM in case you need anything else :-)

I got this error today apon exiting Black Rook Hold.
