I was trying to return some oil barrels to my country at the time, but would also return 59m bushels. I had 123m bushels on hand at the time. Would this have been decay or a bug?

so you had 123m bushels on hand, and 59m bushels on the market that you returned, and after you only had the original 123m bushels?

I didn't memorize exact numbers, but that's the rough idea, yes.

that shouldn't be possible strictly speaking.... if it returned them it returned them...?

They didn't seem to get returne. I did not see the bushel count really increase. They just seem to be missing.

I TOOK EM! HAHAHAHAHA
