Might have finally found a fix for this. I was so upset when I encountered this bug that at level 13 that I went to Wes and kept clicking on his dialog box (not sure what you call this it's the text space next to the picture), which sometimes would show you his contact status and sometimes would tell me he would have tasks for me but no mission link would show up. Eventually as I was double clicking, the words Bonfire in blue came up in his dialog box and the complete or abandon mission link showed up. From there I was able to contact him normally and complete his main story arc. Prior to this I had completed all the non-main story arc quests at level 9 for Wes, until he said the next mission requires security level 10 (not sure if that made a difference as well). I can't guarantee that this will work for everyone (there might have be more conditions that I just happened to fufill with this toon, other than just the double clicking) and I'm not too sure what I was doing myself until the words bonfire appeared. Just wanted to share whatever info I could.
