Current exploit lockpick

[Seltri]

Hey, My name is Seltri.

While leveling my lockpicking to 350, i met a bug 'exploit'. 
 

When you lockpick a box, you get the loot in it in a window. if you close the lockbox.
It's locked again and if you use lockpick on it again. You gain skill up again (infinitely "until it's grey")

That's it.

Have a good day.
