Please add "Trade Route" to list of known card bugs

[elrond79]

I know it's listed in the FAQ, but I initially checked in the "known card bugs" post, and thought it would be there.

The fact that the Trade Route Mat is not implemented, while possibly (currently) intentional, is clearly a problem with the card... and it's nice to have a central place that lists all known issues with cards.

Thanks otherwise for making a very solid game, and helping me and my friends forget some worries during this time of madness!
