Forwards transaction bug

I put 280 fruits in the raw material warehouse before the date asked ( it asked 200 fruits only), and the date came, I got contract punishment.
Must be there 200 fruit exactly in the raw material warehouse? It happened before in round 1.

I read it, it must be on product material warehouse....It is very strange, why not in raw material warehouse?

So you have to move goods to product warehouse before you login again and set higher selling price to stop goods being sold.

By the way, I found that Forwards transaction is useless. Comparing with sold in store, they have the same selling price if the market is not very full occupied. But there is no penaty risk while sold in store.
