I got this error in the console when I drop the flag in a battleground CTF (like Twin Peaks).
Gameobject (GUID: 2134732 Entry: 179786) not created. Suggested coordinates isn't valid (X: 1568.691895 Y: 348.233307)
You need to be sure that you've extracted maps, vmaps & mmaps for this map. (I think maps are enough)
