Everytime I try to drop the F-link it keeps saying I can't because of some ionic disturbance. I've only been able to use it once or twice in Shamazaar and once in Okansankaar. Is it a bug or am I missing something?

If you're trying to teleport to a different area, like from Shamazar to Okasankaar or something, it won't work. You can only teleport within the same area. Also, there are some points in the game where a special event will pop up that you have to go deal with. Teleportation might be limited at those times too, I'm not sure.

I keep getting that message when I'm trying to drop the arrival platform on the ground. I don't have any other f-links being used either. It seems to happen nearly all the time regardless of whether theres a special event or not.

That's odd. I don't remember ever having that problem. Anyone else experienced this?
