OK ...so I have about 600 hours logged on this awesome game....Level 71. A long time ago I forged / grindstoned / enchanted a Daedric bow that was "naturally" DMG 195.....(with some potion enhancements - no cheating)
OK....so now I forged a Dragonbone Bow at the forge that comes out with 186 DMG (Legendary) before I even go to the grindstone..... Then when I go to the grindstone and drink a "Fortify Smithing" potion that has "134%" (all perks in in place trust me) I get "You do not have the skills to do this BS"
I have %100 Smithing and all of the other perks related to this......
I also went back and tried to make a Daedric Bow again and drank the same 134 potion and got "You do not have the skillls...."
I HAVE THE SKILLS! WTF?
