i can use the mod because the Quality from space age dlc is an optional requirement which i dont have.

my question is, what does the skills about quality does if i dont have it? like from artisan skills?

I'm pretty sure I just disabled them if space age is missing. But you do ask a good question, the auto-smelt is behind the quality-focused skill, so I'll see what I can do about that.

I checked and they weren't entirely disabled, they were just giving you the debuffs without the buffs. I fixed that and made playing the base game actually have bonuses. Mostly XP (with the drawbacks kept), but also some boosts to the other skills that can give you around +50% total bonus to those specific skills, like higher motherlode chance. I'm not entirely sure if this balances out in the correct way, so please let me know if you think something else might fit better there. The idea I had was to make the base game get the passive bonuses faster along with stronger special abilities from the other branches to compensate for not having quality.

that sounds great, did not noticed the debuffs since im still low level and did not take any skills with debuffs yet. the new addition is very useful to non-space age users too, thank you for that.

Glad you like it!
