the questtrail is bugged, I guess they added some rockwalls as an afterthough. Just go to the other side of the caldera and start following it from there and you eventually find the 3 spheres. ONe is right to the left from the campfire behind one of the giants.
I guess they haven't figured out yet how to escape the apostrophe in SQL queries. Since the apostrophe is used to end the sql statement it most likely fails to find the character in the database. Should be easy as pies for them to fix. If not...then we are going to have a very bad time.
That (/22) means a range of addresses, in this case it is all addresses between: 208.95.184.0 and 208.95.187.254 So no, you cannot check your ping with that since you don't know against witch one of the 1016 addresses it is.
Atleast the missing doomguards dungeon did this to my companion. As it did with the mobs too. Sometimes she came back, sometimes not. I could get her back by unsummoning and the summoning her again.
