Beamed down with my crew to tag some medical crates. Away team would not respond to commands. Orions only fired upon me when I shot at them. There were two "space" anomalies which were embedded into rock formations and were not retrievable. I was able to complete the mission by scanning and tagging the medical supplies.
Planet W006-Psi Investigation: Inspect Medical Supplies - The Delta Volanis Cluster in the Sirius Block
Beamed down as you described but when traveling around the area all crew members would get permanently stuck and disappear into the large ground structures: Rocks, Boulders, Hills, Trees, Buildings and Mountains. Also the Orion's that were also stuck, in the ground structures, were firing at me but I could not return fire (unable to target enemy); unable to complete mission.
