This bug belongs to the guilds, I'm not going to talk about how to make this bug, but I can talk about what this bug does. This bug allows users to join a guild even if they are already in 15 guilds and do not need Astro or Astro Plus

I have already sent them to gmail to fix this bug

It's not fair for people to pay to get into more than 15 guilds when there's someone else who passes the bug and gets into more than 15 guilds for free
