No Irregular tomestone when joining in progress

[RoyalBeef]

"Hey Bob, you done with what you were doing yet? We're at Gaius and ready to kick the rando healer from the group so you can join to get your tomestones."

I'm pretty sure the majority of MSQ runs aren't done by premade parties of 4+ people who would even be able to pull that off. And no one in their right mind runs MSQ for moogle tomes, just to plot kicking someone before the end to get someone else in.
