No loot in expeditions?!

I will make this one quick. Currently I just ran a expedition event during one of my tier 4 maps (low level I am aware). However, I was able to connect just about every modifier possible. Everything goes as normal, all 6 common colored excavation chest pop up. I finished off the enemies, and opened all my chest. To my surprise not a single item, coin, currency nothing dropped. Like tapping a dry well for a sip of water. I have a it recorded for proof. Again, not sure how i post that here this pertains to PoE2. I would say test it and look. My item rarity modifier going in is 64% and the map had an Item rarity of 18%. Not sure how NOTHING dropped. Not even gold...this cant be right.
