Tenzanar

Just tried an exterminate bounty with the "Find 3 Murmur Sarcophages" requirement. The first sarcophage I opened registered but none of the others did. They all opened, they just didn't register. I tried opening with melee, tried shooting one, even scanned one, the scan was successful (yay 10 Simaris standing) but it still didn't count for the bounty and I ended up at the end of the mission on only 1/3 sarcophages with none left on the map and had to abort losing all progress.
