I want to mod the game using the steam workshop mods, do they disable achievements of the game?

I'm on my 4th playthrough, 3rd with TSLRCM, and I have never played HK-47's side quest until now. Was this added recently into TSLRCM or was this quest available in previous version? My game also had some weird points I've never seen before.

If your intelligence is high enough you can get the dialogue option of asking atris if she regrets not following you to war against the mandolorians

The game does not launch saying that it requires STEAM and that it must be iin the Steam library. BUT IT IS IN THE STEAM LIBRARY AND I DID BUY IT.

I prefer vanilla. Factory was the big addition and it was just another boring combat gauntlet like Trayus Academy that the endgame did not need. I can’t believe the mod gets glazed as much as it does. Some things like the padawan are just downright awful....
