[0.17.9] Sciences (queueble) unlocked out of order

Post by Daringstar »

Note: this can only occur if the science queue is Always available.

Occasionally, at Science pack thresholds, if all tech tree requirements are met, with at least one queued, a science will be marked as queueble despite the science pack requirements not being met. Adding the erroneously available science does not appear to cause any issues.

For example, in science_01.png, Lab research speed 2 is in the queue, meeting the tech tree requirements for Lab research speed 3, which is made orange and appended to the list of conditionally available techs, but Chemical Science was not yet researched (or even available for research).

Steps to Reproduce:
  • Have the research queue enabled
  • Research all Automation Science Pack sciences, except Logistic science pack and (Bullet damage 1 or Bullet shooting speed 1)
  • Add either Bullet damage 1 or Bullet shooting speed 1 to the research queue
  • Observe either Bullet damage 2 or Bullet shooting speed 2, respectively, being marked queueble and appended to the conditionally available sciences list.
Technical info
  • (build 43513, win64, steam)
  • Vanilla

Factorio doesn't stop you from doing stupid things because that would stop you from doing clever things.

Having the tech tree tech lets you queue the research, having the science lets you perform it, there is no requirement in this mechanic to only be able to queue research when you can produce the science for it.

From the wiki:
The research queue is by default unlocked when the first rocket is launched. Alternatively it can be unlocked in the map generation settings in the 'advanced' category, or via console commands (note that this disables achievements for the save).
