the labs are no longer synced up, instead sounding like a din of multiple songs playing at once. I reckon it is to do with factorio's 2.0.39 update where they "Renamed WorkingSound::max_sounds_per_type to WorkingSound::max_sounds_per_prototype. The limit is now applied per prototype."

and yes i've already tried simply changing the api file of the main mod to say "prototype" instead of "type" but it didn't fix it. modding is beyond me but hopefully you can give it a fix! I am running these mods with the LabDansen mod for reference.

Ok I'll check it later today thanks for telling me

just uploaded the update, you can check it out.
I don't have much desire to play the game and test the mod right now, if you find anything else, please contact me
