Missing resources?

Hello!
(^_^)

I had a weird game a while ago. Two Arbies (me included) and some other dude. Enemy quit one after another, and after around two minutes, it was over.
I remembered having destroyed an enemy’s Ghost, so I was looking forward to the scoreboard to see me - RANKING SECOND!!!
=O

I checked, and yes, I had the best military stats. What made me second were the economy stats. I produced 1500 supplies, other Arby 1890. Now, it was a short game, and I was watching. I had Temple and four upgraded Warehouses, Summit building. Same as the other Arby.
So, HOW IN THE WORLD, could he get those additional 400 supplies? My building order was Temple-Warehouse, but our Arbies met, so I think his was, too. And even if his was WH-T, that doesn’t make 400 supplies!
(O_O)

WTH went wrong with this game?

Maybe he collected supply crates?

No, they have a separate coulumn. I checked them, anyway, he had 271, me 270 (where did he get ONE supply???).
