We are aware of an issue regarding the Ninja Advancement Tests. Since the Ninja Revamp update, you cannot advance Kunai Storm and Shuriken Charge to Dan 1, Dan 2, or Dan 3. We have forwarded the issue to our developers. In the mean time, PLEASE DO NOT TAKE ANY ADVANCEMENT TEST FOR NINJA SKILLS.
This will be fixed in the 11/16/17 maintenance, so there is no need to submit a ticket.
Thank you for your understanding and we apologize for any inconvenience.
