You should know by know that on our server all event ninjas that get BTs will need to be at 4 stars. Oasis changed it from the original 3 stars in China.

When they add updates, there are chances where coding messes up and it goes back to the original coding and it takes people to tell them about it to change it back. Changes like seeing unreleased bts from ninjas they did not announce, unintended prices in events, and the Killer bee situation are all examples. Just learn to be smart and not report it to Oasis about the mistakes in coding if they benefit the players. There's too many not so smart people who report bugs and ask if it is permanent.
