Found an issue where the game will say you are teleporting but you won't actually be able to.

Date & Time: 10:30 AM PST 1/151/2022
Frequency: repeatable

Steps:
1. Open the teleport menu and mount up
2. As the mount up cast is close to finishing, click a location to teleport

If done correctly the teleport cast will not start and you will not be able to use the teleport functions due to the game thinking you are already teleporting. The only ways I have found to fix the issues is to zone into another area, either through connected areas or through Duty Finder. Moving and casting another spell does not seem to clear the teleport queue.
