Perhaps reducing the modules was a bit too much of a nerf. Now kiln has maximum 125% productivity, and when comparing to some other mod buildings like calciner from Pelagos that has 50% prod and 4 module slots (also higher speed) all at common quality, kiln kinda look a bit weak. I understand that balancing against other mods is almost never a reasonable goal, but even unodded buildings like foundry can reach 150% productivity bonus. Maybe give 50% prod bonus on top of modules? Or increase modules amount slightly.

I may still adjust the kiln more, but I'm definitely happier with it now than before the nerf. The kiln is the "lesser" of the two unique buildings, with the pressure forge being the "greater" one. E.g. it's like the recycler rather than the EM plant. It's also not meant to compete with the foundry, but with the electric furnace for things like stone brick and lithium plates.

Yeah, i agree, it's definitely more balanced than before. Just a thought.
