You can add some annoying bugs:
the beastmaster of Balmorra. It seems to be impossible to get the "Mutated Colicoid" .
"The Foundry" Endboss kills does not count.
The old classic 16 Raids kills does not count.
Sorry, not sure what you mean, are you saying no 16 raid achievements are working?
Jenzali, didn't know that rule, but BW haven't removed the post... yet... If nothing else it shows people which ones are bugged so they don't waste time searching.
