Great mod! I use it in every playthrough. In my current game with the Factorissimo2 mod (along with several other mods), I've had a few occurrences of this minor (non-game-changing) error. Sometimes, upon entering the Factorissimo building that contains the labs, I notice they aren't strobing with the colorful animations (even though research is progressing normally and the crackling electric noise continues). Mining a lab triggers the "DiscoScience detected an unregistered lab" message. Mining then replacing each lab fully corrects the problem, including restoring the animations. I haven't yet figured out what might be causing the error, but it may be related to losing/restoring electrical power to the building. (I'm not even 100% sure Factorissimo is the culprit.) Let me know if I can provide any more information or logs.
Thanks!
