Auto delete offer messages on accept/reject/retract (Fearless Blue)

Consider adding a option in the settings that would automatically delete messages offering products on contract or for immediate purchase when the offer is closed (accepted, rejected, or withdrawn). A similar option could be established for messages regarding building a company in a player country.

Would be a good idea - but it would also be good to be able to fix the different purchase/sell/contract logs because some of them seem to lead nowhere in-game.
