Melee riven mod not unveiling

[Ragnos1435]

I have a melee mod that requires maintaining a x3 multiplier with an active pet for 30 seconds, and despite fulfilling it an number of times in solo and in multiplayer, with various melee weapons and different types of sentinels, It has failed to unlock. The sentinel has not died in most.

If it says pet, I think that refers to the kubrows/kavats/charger and not sentinels.

I'm having similar issues. The phrasing on the melee mod is "Maintain a 3x melee combo multiplier for 30 seconds with an active companion present." I've done it with different weapons, different warframes, and tried both a Kubrow and a Sentinel (don't have Kavats yet). Every time I load into a mission, the challenge shows 0/1, and does not trigger completion even with several minutes at 3x multiplier. This is more annoying than the mission challenges that fail to track progress (and thus are impossible to complete) that happens every now and again.
