I'm sure most of you are familiar with upgrading items through smithing.

I had the Krosis mask, and I upgraded it's armor rating because it's a really good headpiece, even more so upgraded.

I eventually got the other masks, so naturally I went to the Labrynthian to get the 9th mask. When I placed all the masks, grabbed Konahrik (spelling?), and put Krosis back on, I noticed that it was reverted back to it's default rating. Of course I was able to re-upgrade it, but not everyone may be able to get more Blacksmithing potions (they are pretty rare).

I just thought I'd let everyone know.

Thanks for the info.
