Stop Watch refunds it's worth on sell

Hey,

So when I sell my stopwatch either broken or fixed: I get the money, then an instant later, the money is deleted out of existence. I can undo this and repeat it again and again . . . but the watch constantly and will always never give me the money to spend. So is this a feature or is it a bug? As a support, 300G is like . . . a big fucking deal.
