This afternoon, I have been unable to enter a gate (any gate, any tier) from the Arcade. The popup menu appears, I make my selection and hit the blue down button. Nothing happens.
I have been able to join friends already in the clockworks.
Update - fixed
Seems to work sporadically. For now, my workaround is to change an option so it cancels (such as clicking on a different tier button then back) and retrying until it works. It doesn't take too long to get in.
We took a reboot to fix this and the guild halls that were broken for a few guilds. So it should be working now.
Same here, though it worked when I tried it again a few minutes later.
