The Farseer engineer requires Meta-Alloys for us to be able to talk to them.
It seems that the barnacle sites dosen't spawn them atm.
Some people thinks its a bug, I think that we have to look somewhere else.
I think I will look for them in nearby wrecks, nearby systems, space wrecks. There is also reports that some barnacles is protected by turrets ect, but they don't drop meta-alloys, just normal materials (maybe there is a random chance that they do).
Have any of you seen them?
