The following 2 metafields in easyPoints will not update automatically upon tier rillovers.
loyalty.tier_maintenance_spend
loyalty.tier_advancement_spend
Even though the amount gets updated upon order creation/fulfillment/payment (depending on the setting), the amount will be inaccurate in certain conditions due to it not getting updated upon tier roll overs.
