I crafted a Deadric Sword today and enchanted it with Fire Damage and Shock Damage. I used a full Grand Soul Gem. After I made it, I went and attacked an unkillable NPC to see how many charges it had (ie how many times i could swing it and hit somebody before the charge completely ran out). It turns out it had 150 charges/swings.

I saved my game, exited, and came back later that day. When I loaded up my file (the same exact save after I made the sword and counter the 150 charges), the sword's value had gone up 600 septims and the item ran out of charges after 43 hits instead of 150.

I tried it over and over, saving and reloading. Every time I exit and reload Skyrim, the Sword bugs and goes from 150 charges before I quit, to 43 after I load it back up.

PLEASE HELP
