Datamass losing it's marker after Sentient Attack in Lua's Mobile Defense.

[SargionMagara]

So i was doing Thrall Hunting with my friend, and as his Lich is still the one before the whole Sisters of Parvos update, the lich still resides in Lua. We went for a Mobile Defense mission, and after the 1st data console, Lotus mentioned that we need to clear the Sentients first before being able to continue with the mission, and since that moment, the map doesn't show the marker for the Datamass anymore, and we couldn't find it in the end. Quite the shame since we have to abort after we've collected quite the murmurs and some Drift mods too along the way.
