Third win in a row reward

[Intoccabil3]

I defeated Tigerous the third time in a row, the choice for the additional reward didn't prompt after he gave me the rewards and the consecutive wins reset to 0 without me getting anything from him... I know for sure I had the right difficulty thanks to the damage I received and the fact that i got roughly 25k from the victory. I understand the reward is now gone, I just wanted to report the bug so that it doesn't happen to someone else
