@Ebon Prophecy, yep I did all that, logged out, left the station and back in, figured maybe it was just an odd bug and waited until morning when a GM was on and it still wasn't there.
@Dev Zoom, I figured that may of been the case it went to a different station than the one I started out or took the mission out of.
As for your question, nothing weird happened. I killed the 3rd one required and it gave the normal mission complete popup box. I went the the station and did not see my Yagel, I did the above steps that I listed to to Ebon before I contacted GM Tornado.
