Re: Make Them Come To You - Kylo Ren milestone not updating

I finally completed this Challenge tonight in Co-Op mode. Oddly enough, I started having better luck after un-equipping the Pull-related Star Cards. I still was only able to get credit for only 1 or 2 Pulls per match, and sometimes no credit at all, despite using Pull against multiple enemies. It probably took me about 6 to 7 hours to get the last 19 successful Pulls I still needed for the Challenge.
For reference, I completed the Challenge on Takodana, at the last capture point in front of Maz's castle. The door had just opened, and several Resistance troops were heading towards me when I used Pull against the whole group. I probably got 4 or 5 enemies with one Pull, and the Challenge Complete message appeared while the enemies were still in midair.
