...... and this problem still exists...
I have been trying to get a sample from the new Orthrus type Thargoid and out of over 15 attempts.... nothing.
Tried everything I can think of, from only using a single limpet at a time to multiple, sitting stationary when they return, moving fast when they return to me... and all for nothing, I have no got a single sample back from a Orthrus.
The voice over tells me extraction was successful, but when the limpet returns to my ship, it disappears and the dialog box in the top right says "Research Limpet Failed".
Frustrating to say the least, specially since taking a sample from the docking point on the Caustic Generators was without problems.
