Preying Mantis Achievement Won't Pop

Hey all! Recently 3 friends and I completed the terms of an achievement but it didn’t pop for any of us. For the uninitiated:

> Complete Swords of Sanghelios co-op with both Mantises on Heroic difficulty.

Our mantises survived until the end of the mission on heroic difficulty.

Has anyone else encountered this lately? Any suggestions or tricks on how to get this to pop? I’m hoping to wrap up all the H5 achievements by Spring.

Maybe ask 343 to help your issue out, they probably would give you a good answer to your dilema . I know they, 343, doesn’t respond to players issues when they ask for a fix on waypoint, but being a monitor i would think you have a better option. good luck

We just popped it yesterday…did u bring the Mantises into temple to the Arbiter? Tho i think it popped as soon as the Mantises walked in…don’t remember

I didn’t know if I should use the black phone or the red.

I didn’t bring them into the temple. Will have to try that. Thanks for the advice!

To follow up, that worked. We needed to walk them up to Arby instead of chilling outside. Thanks!
