Can't succeed 7.3 Artifact Mission
Device: PC
OS: Window10
Description: To complete this mission, says you have to win a 4* or higher gauntlet with HP % as the main stat from stage 4 of Kaerok Castle on Hard or higher. I have received a 4* or higher gauntlet with HP % as main stat many times but the mission never succeeds. Below screen shot shows one that I captured on Brutal. Because it never succeeds I cannot procede with any other missions.
