Am in Inverted Spire August 7th @ 11:56pm mountain time. Got through solo legend Inverted Spire up to the unstop and anti barrier fighting where that tank can spawn. Right before the crator section. Killed them and all the crater enemies. Then noticed the push forward objective was behind me. Went back and bagged the marker, slid past it, ballistic slammed it. Nothing.... very frustrating plz halp.
