Add on for IR3. A new game start is recommended - this add-on was not intended to be installed mid-game.

Some technologies aren't researched by labs but are unlocked via inspiration. Inspiration occurs when you handle or produce a new material, or complete a combination of prerequisite techs. This new mechanic is similar to the "research trigger" feature in Factorio 1.2 (but I had this system finished before that was even announced).
