have you tried both entry points...the place she took you to talk to,in the graveyard...and the bottom entry where the food is...
i never tried the bottom way so dont know if this opens..
but i did get the bug where the door was locked in the graveyard entrance

damn, just enter the far up and leftest tomb at the graveyard map!!!!.... not the egyptian pyramid tomb...

YEY!!!, can I just say I love each and everyone of you
