Q:
captured dolyaks are walking to next map
You get credit for capturing the dolyak calves at the time they become pacified (the bound hands icon pops up), not for ushering them through the portal, despite the way the task’s description is worded. The notion that you need to keep them alive until they reach the portal is false. In actuality, the benefit of ushering the calves to the portal only comes from the opportunities to kill the skelks that try to attack them (which gives you some additional credit for the heart), but whether the calves live or die—or reach or not reach the portal—is irrelevant.
As for something changing with the J28 patch, I don’t know. I did this yesterday while doing the new content, and it worked as it always has. If you’re supposed to get credit when a calf enters the portal, I’ve never seen it happen, before or after.
