In master lvl of Going all in - Downtown, the challenge "Keep all Fighters above 90% HEALTH" is not working on the mission where only silver fighters are allowed and where we need to face an Assassins Greed. I`ve completed this challenge 3x with 100% HP with Greveyard Shift, but the game didnt recognize the challenge. The other missions seem to be alright, since I completed 2 of them after the 4.3 update. Edit: It was my mistake. I should stay above 90% Healt all the time, and not just at the end of the fight. I already get the challenge. This is not a bug, but I think the challenge to finish under 120 seconds in "Ascent of a woman " mission for only gold Beowulf is almost, if no enterily, impossible! I am able to finish this fight almost all the time I try, but I am still far from achieve this challenge, even with Full Beos (even a Wrestler-X) and all moves in lvl 9+.
