Stuck turn thanks to "unknown civ 15"

The game continues to run "normally" but the turn wont complete the turn, being stuck on "unknown civ 15".  current version - 55.whatever

At first I thought it was because of completing the mission that give you two farmers (I can't recall the name w/o opening the game again)  But postponing the project did not solve the lock.

Thanks to console commands, I found out its the Iconians, and they look like something has totally gone bonkers as they have only 3 plants (to my 30) and it appears their stardock is full or something.  I can literally delete the 4 planets and the game will continue normally.

I have the 3 previous saves if it helps:
