Fix the glitch where if you apply to a clan then a different one it greys out the first clan and you can no longer apply.
I don't know if it is actually a glitch or intended. Seems like to me it's intentional. As an example: understat acc applies to the clan. They get rejected. Instead of that small acc being able to send a million join requests, they can't because the button doesn't work. There are other causes of abuse but I find this is the most applicable. Unfortunately it does cause problems for those, just wanting to apply. But it's the lesser evil I guess
