I have an Aethermeter now when I didn't a moment ago.
I entered a fight and it wouldn't load, so I closed the window and reloaded the launcher. When I next entered, I had an Aethermeter which would fill up with Aether. I can use the Aether to clean lampposts.
Before (another glich, perhaps, is that as soon as I log in, I can't see my profession badge next to my name, but other people can see it on their ends.)
After (with Aethermeter):
When I log out, it doesn't go away. When I restart the launcher, it doesn't change either. Entering a fight does not fix it, and I can use the Aether to restore my health. Changing rooms does not seem to fix.
After entering the Beacon and logging out, when I logged back in, the Aethermeter was gone. (You can also see my missing badge upon initial login here too):
I'll try to see if this glitch is repeatable.
