4 days ago I had well over 2000 boosts saved. Then it mysteriously dropped to 643. After receiving more boosts to the amount of 666 in dropped again to 654 and keeps going down. My tribe mates keep sending me boosts and I'm not using them but the number goes down. This is not only and issue with me but other tribemates as well.
