It looks like a couple of entries were wrong. I don't know where I got my TOL Artifacts but they are a little different. It is odd because on WallOfHungryMouths it is written as this pack - this.AbsorptionAttributes.EaterPoison = 20; Very strange... but mine do work.
MoctapotlsObsidianSword.cs
Mine:
WeaponAttributes.SplinteringWeapon = 20;
This pack:
AbsorptionAttributes.SplinteringWeapon = 20;
JumusSacredHide.cs
Mine:
SAAbsorptionAttributes.EaterPoison = 15;
This Pack:
AbsorptionAttributes.EaterPoison = 15;

Also as for copy/paste from the error screen, I left click on the upper left corner of the console window and get this menu
