Another trade issue. I'm deliberately over producing manufacturing as there are buyers, but as the point that it went into overproduction and shows that I have a token in the supply-demand window the trade window shows I have one availble token in offices and none in manufacturing.
The trade window really needs to give much more data about the cost the player incurs to produce each token - so they can be sold for a reasonable value. It also needs to show the accrued income from active contracts.
