I've lost at least 9 or 12 tomestones this way. You get the MGP from the pool but not the Moogle Tomestones, which is a weird bug. I still haven't been compensated for this as far as I'm aware and bug reports been completely ignored in game. Because it's so visually overwhelming being on that platform I sometimes end up missing the safe spot and walk off instead. Which then just becomes a waste of my time
