Treasure Hunt build option *poof* gone. / Lag at 11520 x 2160?

Intrigue installed, over 3100 hours played overall.  I built one treasure hunt, got the message for ~250 credits, went to build another, and all the options, for say helios ore, aboreum whatever, treasure hunt, (early in the game yet there were only 3 options I believe), gone.  Not listed at all.  I can build a colony ship or a constructor ship, and thanks to the new.  ahem.  government rules, I don't have the space for colonies at the moment,  so shipyards are starting to go idle.  was there a change or something, treasure hunt goes out for 5 turns or something that I didn't catch?

also, anybody notice any lag at way high resolution?  first world problem here, I know, I'm used to playing at 11520x2160, viewing the game on three screens in GLORIOUS mode.  After intrigue, when I go planetside to bui l d t he qu eue i f there's a mo on i t stutt ers.  I could have sworn pcpartpicker had a way of creating a link to my handcrafted build, so I could satisfy the "well list your build!" here, even though I know it's sufficient.   More of curiosity than anything else, really.  This game ever goes VR I'll never go outside again.
