hate to bother ya.
im guessing your working lockpicking.
just thought id let ya know that you only need 1 chest if that is infact what you are training.
that old code for using trap boxes that made you use a new one till you gained or you would never gain was chucked out a couple years ago.
hope that helps.
and i can make ya one if ya need one still.
but i cant do 50.
just dont have time, sorry.
