Zone Not Loading... Well, it does... but...

[Ravenflight]

So I made a Dark Elf wizard, ran around, turned in my note, memorized my two spells, and made my way to Nektulous Forest and zoned in... But...

When I did - there was no floor, no walls, no sky - and everything was a light green haze (except my character) - and PCs (and NPCs, such as monsters) kept doing the falling through the floor animation (although there was no floor, so they seemed to be plummeting to some green, hazy death, far, far below... but then would reappear, and then rise and repeat...)

Tried camping and logging back in. Didn't work. Tried exiting out all the way, and logging back in fresh. Didn't work. Other zones (for my other characters) work fine.
