I can't build anymore anything (on many systems) as food and industry is marked converted to science despite the fact I have not chosen to do so. Here I'm trying to build something and it is impossible.

I suspect it happened when I discovered Urgent AI research technology while the earlier science conversion "building" was in the contruction queue (not necessarily at the top of the queue)

Version : 1.0.52 Hotfix, Riftborn

EDIT : I confirm, if you have "planet cracker factory/lab" in your construction queue when you finish to research "Urgent AI research" all systems will then be stuck on converting industry to science forever without being able to remove the conversion form your queue (not displayed). The only workaround is to get back to a previous save and remove the "planet cracker factory/lab" before discovering the technology.
