Galactic challenge momentum feat not working

Same for me, feat not finished although I won the fight and had almost 270 stacks

Still not working. Missed out on red box last time, gold box this time. Boo!

In the last event the same thing happened and I was harmed.

I'm confused by OP's details, so I want to mention it to make sure you're aware.  The 150 stacks of momentum don't count whether it's 3 tuskens x 50 stacks each and it doesn't count when it's 1 tusken at 150+ stacks.  I can't confirm if it's failing to count when 3 tuskens are at 150 each, but then, I don't think that's what the challenge intends.  I've had stacks at 147 and 148 where my next attack with t. warrior should've put me over, and stacks of 150 and 153 that didn't count towards completion.

I have done it several ways.  And I think the issue is the wording,   believe it should read FINISH with over 150 not gain.  I have collected up to 474 total and no credit.  And in addition had 184 on a tusken committing the finishing blow once, and it reset to 14 stacks and no credit.  So was clearly "over 150", but with it resetting to 14 and getting no credit... feel like it MUST be complete it WITH 150 stacks.  

I believe it’s multiple issues. I think it’s over 200 and the lead ability doesn’t count. 

@EA_Gunner this issue was brought up last GC and actually cost me a valuable omnicron. If this couldn't be fixed, another faction should have been chosen. It'd really be nice for a minor make right (still waiting for one on the GC with Malevolence sans cooldown as well).

Same problem as last challenge. 150 stacks of momentum is not granting the feats. I’m guessing it’s 200 again?

That would be a no as well.  Literally over 300 stacks twice during the battle, and still no feat
