Another Tweak from me :)

I've been enjoying the quality mechanics in factorio. Vulcanus has easy stuff with liquids and quality drills, Fulgora gives you the 5 module slot EM plant, and aquillo has an 8 module cryogenic plant. But Gleba really makes it hard, especially with spoilage.

And I also noticed that the agriculture tower has no reason to increase its quality (it just gets more health). So i throught it could benefit from a innate quality bonus every time it increases in quality. This allows you to kickstart the quality chain from the towers and not just the bio chambers helping speeding up the process on gleba. feels good for me :) I went with:
-common 0% quality (nothing changed)
-uncommon 5%
-rare 10%
-epic 15%
-legendary 25%

It feels vanilla for me and also controllable without modules. If you want to avoid quality products, you can keep the vanilla experience by using common towers, if you want to build a quality factory, you can start using the quality towers.

Let me know how its goes!
