Technology foci change without my interaction.

They will all improve but the ones you focus on will improve faster.

Ok, my mistake. I will try to produce it myself but please keep me posted if you get any more information on it. A save would probably not be of any value since you're saying that it didn't happen again. Just try and reproduce the possible steps of the game and see if it has any effect.

Thank you for taking your time doing this.
