Title says it. Is this still a bug I have seen reported previously.
I have tried the suggestions to reload to see if the Chiron changes type. It has not.
The captured Chiron is at the 2nd base Containment not at Phoenix Point.
The Research is still greyed out.
I’ve had this in the past. But I’m not sure if it’s because the creature had already fired all it’s rounds. Thus it doesn’t contain goo anymore.
It can take several attempts of loading the autosave. Sometimes one is lucky and the 1st load works, but I have had to do at least 4-5 tries (and maybe 6 in one playthrough).
