Well I done did it both ways in Word and they both pass.
Including the "I done did it" phrase. It still passed.
If you elect formal grammar check it barks at "you'll" to be "you will"
But "done did it" is still okay. Heh,Heh,Heh

BTW,
I don't think this is really a bug since you should be able to correct it in a language file. I think?
