After the last update, the arena is inter-server on server 1554, but its marker shows that the inter-server is 29 days away.

I did a test, I tried to find a ranked battle, but I didn't find it so easy. When I tried the training battle, it was direct against ninjas that I know don't have on the server, much less ninjas with breakthrough skills.

Could you tell us if it is just a bug and will it be fixed or is it permanent?
