[Doctor Steffard Won't Spawn In Imperial City]

I'm experiencing the same issue.

 

Have you done the interrogator Kang mission arc?

 

If so, this may be the cause: https://paragonwiki.com/wiki/Doctor_Steffard

 

If doing all the arcs for the badge; I think you may able to complete this arc via ouroboros - (If anyone can verify, that'd be great)

 

 

[Defiant Roll Call]

Defiant here too

 

AC-DC was my main elec/elec blaster, not after the band ;)

 

Gamma Base was main SG, with affiliations to Karma Police :)
