Guild member can’t join

Invite Pending as you can see here

You can also check this topic if you want proof that the poster invited me 10 hours ago

Taisiakat’s solution might work, but since Elarcadia (the person who tried to recruit me) and I aren’t from the same time zone, that won’t be an option
