Carry Weight Glitch in Skyrim
K, I'm gonna look like an idiot answering my own question, but I figured it out. It seems to be a bug with the Extra Pockets perk in the Pickpocket Skill Tree. I made it legendary, and as soon as the perk was removed, it was back to normal again. If anyone is looking to have 15,084,303 carry weight, you can do that apparently, but I am not sure what triggered this.
