NINJA GAIDEN 4: Chapter Challenge Being Bugged, Fix Please (Workarounds)
Short answer
Suggested fix (unconfirmed): Verify your game files through Steam, then replay and complete the chapter again while connected online.
The problem
When selecting chapter in challenge mode, there's sign showing if the player has cleared the chapter with yakumo or ryu, death wish and untouchable. I cleared chapter 16 with yakumo for 3 times, but there's no sign of cleared, the sign of yakumo is still dark(normally it will turn red). The other chapters are normal.
No confirmed fix yet. Players suggest: Chain Link only works when the player holds the block button after dodging and input the next attack button after that.
