Modding in any way shape or form will break rule 11 with Tuxborn, anything you break is on you and if you need help stick the to modlist-modifactions and not the support channels of Tuxborn. The same is true if you want to know how to remove something. If you are new to modding or now to mo2 look at the guides at the end of the readme. What you find on the page is some info and tips on how Tuxborn is put together and how that is related to Rule 11 it.

Just watch this

Yes realy watch this, https://www.youtube.com/watch?v=izGoHgO4izc

Mo2 Profiles

Profiles are one of the unsung heroes of using mo2, make good use of them. Never edit one of the base profiles, instead make a copy and start going hog wild in there. If you plan on changing a lot of stuff make a back-up copy of your rule 11 profile whenever you hit a milestone.

World map

We use Flat World Map Framework to replace the map Skyrim uses, this mod doesn’t like to be overwritten by anything. So make sure anything you added is above it on the left and right side of mo2.

Where should I place stuff within the load order

At first at the bottom, that will make it easier to check for any conflict with xedit. After you checked and fixed those, you should place them in the same place as similar mods.

Turning kill moves back on

Remove the no kill move esp from blade and blunt + hide the auto run file you can find in Tuxborn settings.

MCO based animation with BFCO

Yes you can do this, but you will need to patch them to work. A quick google should point you the correct way.

When should you rerun the Grass cach

When you have made marjor changes to a wordspace or added new one, if you want to. Another easier options is disabling grass caching if you pc can handel it, only way to know is to try and see (see: https://www.nexusmods.com/skyrimspecialedition/mods/42161)

Ini settings keep reseting

Yes that is normal, a dll is changing the settings hit a fps target. Disable FPS Stabilizer to 'fix' this.

Changing Inputs on BFCO

For keyboard: BFCO mcm does powerattack, TK Dodge mcm does dodge, Dual Wield Parrying SKSE and Valhalla handels the extra blok key. With a controller this is also true, but you will need to make or find a controlmap.txt. This is a pain and needs you to edit all the input codes by hand, if you make error with your game will CTD.

Know how to use MO2 and read the info it gives you

Again read the guides from the readme of search for a good vidoe guide, MO2 gives you a lot of invormations that helps you to prevent and solve issues.
