Error — Something broke, and we don't know why ¯\_(ツ)_/¯
Whatever it is that happened, we didn't expect it and couldn't handle it. Sorry about that, try going back to where you were before and giving it another go. If it's still an issue after that, do please send us a support ticket with the details so we can investigate further.
Technical Info: This error is literally at the end of the line of all known errors so by the time you get here, we've got no idea what happened!
