Hidden option (bug? secret?)

[iTeddyZ]

On the NW pillar of the ge, when i right click it i get a "go to grave" option
what could this possibly be?
its strange because i can only right click that spot sometimes. it doesnt show up all the time

its not only me because i google searched it and found only 2 searches on the RS forums

I believe it's the gravestone update recently. It could be a bug.
