Okay. So this is the summary of what I'm gonna use;
Mod Settings
EasyEdictLibrary
CCModpack 5.0.4 + FastCutins
KP Mod
These I will still have to test (just tweaks that can be easily removed), but I will use them in my next playthrough;
Hide HUD
Jerk Bar
KP Deviancy
KP Gloryhole Lockdown
KP Guardplay
Receptionist Assistants
Conclusion of tests;
If you intend to use my modlist, especially the second row (tweaks), take in account I haven't fully tested them yet, so make saves. If I remember tommorow, I might update after I try playing it for a bit (without using cheats etc to zip through the game).
One upside though: It seems whatever FastCutins is doing is another QoL improvement, which might one day make modding even more smooth (and remove that first load error I mentioned before). Just a hunch. Very rudimentary testing.
