You forgot the word blue in your post (you still have a red boss, it's just very difficult to reach).
It was posted in beta too in this thread (it affect level 10 to 12) -> no fix by Inno.
And I don't expect any to be taken anymore because:
- This is the weekend. Most (all?) Inno's developers do not work till Monday
- (on live) this is the last incursion of the championship. Once dev are back in office they can fix it only for America and only on level 12 (in other countries the incursion end a max of 2 hours after dev start work on Monday).
