Thank you for the report. I've passed this information along to the team.

It is doable when you do not have the techs prior to obtaining it. Otherwise the trigger is on unlocking not owning, which is ts ts ts bad gamedesign! =D

I have a save where I may have encountered this problem.

Climate Engineering finishes on the next turn but, when I go to the next turn, nothing happens.  And when I say "nothing happens," I mean literally nothing happens; queues don't progress at all making it as it I never actually hit End Turn though it increments the turn count and makes an autosave. Maybe my issue isn't quite the same thing.

Potential End Turn Bug.sav

Also stucked with this problem. I have EI tech researched earlier and then got the quest. After I researched CE and quest has not finished.

yeah that's end turn bug, probably AI stuck in talks or something.
If you really care about that playthrough, you can always try going debug, switching to the AI stuck in talks, and finish the talks, switching back, and carrying on... :-D

Yeah, upon further inspection, I was getting that problem under completely different circumstances.

We're testing a fix for the quest issue, so hopefully we can push a hotfix for this soon so you can finish the quest. (I will have to double-check if it applies retroactively, though. I'll get back to you on that.)

Great job! Thank you for your response.

Yep, I have this exact same problem.  I already had one of the techs finished, glad to see it's already being worked on.

We just released a hotfix. Unfortunately, it's not retroacive, so you'll have to start a new game to finish this branch of the quest.

GREAT!
