Summary / Title

Any type of industry-to-X conversion can stucks at some conditions.

Description

If you have Construction Queue looking like

<Something>

Planet Cracker Factory/Lab (bacic ind-2-sci conversion System impovement)

and for the next turn you finish researching Autonomous Mining technology with Urgent AI Research which is a replacement for Planet Cracker Factory/Lab then your <Something> stucks with infinity number of turns to finish (if you have in queue only Planet Cracker Factory/Lab bug doesn't trigger though).

Actually, queue not just stucks but the whole star system starts to produce 0 (zero) Industry from now on with no way to fix it from this point (at least as Unfallen). Bringing Urgent AI Research to the front of the queue and removing it doesn't return your normal amount of industry production - it's still showing as 0. Adding Urgent AI Research back turns your industry to negative values (giving you proper science boost though).

Steps to Reproduce

1. Start to research Autonomous Mining.

2. At the last turn before research is complete add to star system's construction queue something to the first place and Planet Cracker Factory/Lab to the second place (see screenshot #1 or Delphinus system from the savegame).

2. End turn.

Reproducibility

5/5

Expected Behavior

Construction Queue shouldn't stuck.

Version

1.0.1 S5

Notes

I noticed it in my case with industry-to-science conversion, but appears like it happens with any type of conversion. Not so big deal in you manage to notice it at the right time. Adding Urgent AI Research to queue  in next turns after it's researched doesn't trigger the bug. So you can just remove ind-2-sci conversion from every queue for the one turn and then put it back after it'll be upgraged. But bug is very pesky and can force you to load old savegame if you notice this too late.

Looks like it happens with all conversions, if you upgrade a conversion, like the Vs for dust, the game thinks the previous version is still in the queue. Was able to fix it, by detaching the Ark.

LOL, Vodyani appears not only the most bugged faction ATM beacuse of Arks mechanic but it allows them to avoid some bugs even.

Added some of your info to the post, thanks for the replies.
