Probably by design but I'll throw this out there just in case.

*LOG SNIPPED*

I flew from one area into another separate area, which if this isn't a bug, is the only place in the mud that behaves that way (that I've seen).

Typically you have to fly up, then fly down from separate areas.

And not the only area that works like this at all.

It's all about what shares the same skies.
