Meebles Glitch

So this happened to members in my meeble static 3 different times now...

6 members all check their stones before the run, we all have 5 ready to go. We complete 4 runs, and then when we go to sign up for the 5th final run, some members will have 1 stone left (as they should) but others will have no stones left. 1st time it happened was about a month ago, and happened to two members. 2nd time was a week ago when it happened to me. 3rd time was yesterday when it happened to one person.

Just some quick notes for anyone who wants to brainstorm any ideas why this is happening:

-I am always the leader who takes us in.
-We do not use multiple grimores
-No members have done any runs outside the static

Just wondering if anyone else has experienced something similar or has any ideas of why this is happening :(. Saddest part is yesterday we were 1 run away from getting our 100k bodies, now have to wait until tonight! QQ
