Can’t complete runescape quest

Hey, I can’t continue with the quest ‘A voids dance’ because on clue 3, where I need to dig on a flower at the Edgeville monastery I am unable to stand on the tile.

I have used the Wiki, which even states the quest cannot be completed because of this point.

I am definitely on the right tile, and have spent the last 10 minutes trying to use ability’s such as Surge to force my character to the inaccessible tile.

I’ve submitted a bug report, but does anyone know how I can continue this quest? Or a way to get onto the tile, I really want to unlock the full rewards from the quest The World Wakes.
