There is nothing wrong with either of these engineers - i have unlocked them both.
You need to fulfill two things for an engineer to become available:
1. you need an invitation (eurybia blue mafia for example);
2. you need to GIVE THEM SOMETHING - it is listed in their conditions. Liz Ryder needs 200 units of landmines and The Dweller needs 500,000 cr.

Hmm - that doesn't confirm there was a problem - but yeah okay if there is a bug - it hasn't hit me...so maybe i just lucky!!
Note that Dwellers home system Wyrd has 3 of the 5 black markets needed to unlock him. Ignore the counter, you need to log in/out for it to update. Use your status-> smuggling statistics if you've lost count.
Did Liz recently, if you mode switch a few times it should pop the invite mission from UBM. (Unless mode switching is against your morals in which case enjoy flying back and to for an hour or so.)
I was one of the people that filed an initial ticket on the dweller being bugged. He is not. It's more to do with the 'state' of the cargo then the actual cargo type.
Below is the answer:
The cargo has to be 'stolen'.
Technically in Eurybia, they are the policeI don't know what mode switching is. The funny thing about this is I got the stolen cargo I used to unlock the Dweller from the Eurybia Blue Mafia by accepting a "smuggling mission for fun" from them and then abandoning the mission and stealing the cargo. I doubt they will file a police report
Well you stole it from the mission giver. They gave you cargo to deliver, you didn't do that and kept the cargo. TheftInteresting since I didn't steal anything. Just abandoned missions that gave me cargo then flipped the cargo to the blackmarket and paid the fine. Guess they consider that stolen.
Re The Dweller. I bought narcotics and then went to 5 other systems and sold them at black markets. It was showing as 0/5 on the engineer panel. I googled it, read some workarounds and thought I'd just do it another time and just did other stuff in game for a while.
Logged in today and had my invitation message from him.
Update in case anybody else has the same problem. I logged in today and I now have access to the Dweller. Apparently there is some sort of a delay in recognizing it. With Liz Ryder still no access. I'm wondering if I have to travel to a particular station to gain access to Ryder. I've been cordial with the Eurybia blue mafia for a few days.
