Adding (Hat#hL) to your name with the Ruby power will grant you the Wigs pawn without ever owning the power. I have reached a conclusion that the key to this bug is Ruby.
I've tried this with other various pawns as well, Those who did not have the Ruby Power were not able to recreate this bug.
With the Ruby power disabled, it still functions.
I have done a Wigs Power transfer and trade back and the bug remained.
The True Key is the Power to auto-update with the new powers as well as having the Ruby Power.
