GM Blog : Coming Soon: "The Battle of Crimsonwood Keep"

Glitches are a definate.

NLC had boomers.
The mansion had the Loki Boxes (though that may not have been a glitch per se)
Phantom forest had bigfoot

But as long as its not anything game-shattering ill be okay with a small glitch to be fixed later on
At least have a little faith in Nexon
