I have the janky quality mod installed and quality labs don't seem to get the productivity bonus? Seems to affect all buildings.

I believe you have confused this mod for laboratory productivity research? The way you describe it makes it seem as the quality labs are not getting extra productivity. This mod does not touch with any lab of any kind

Wrong building, i meant quality furnaces do not appear to benefit from productivity bonuses.

Got it. Looking into it as I already suspect the issue.

Upon looking into it, it seems as though quality furnaces work for me? Can you be a little more specific about this issue, such as what recipe should be getting the productivity, exactly what type of furnace it is, etc please.

Hi there, I found out what it was, it is a visual bug after while you have the crafting window open when looking at the furnaces, after I close the window and reopen it the productivity works as normal, nothing to see here move along!

Oh great! Enjoy
