CivUP & GEM had amongst their goals the desire to fix some errors that Firaxis missed. So with that in mind could we look at these 2 bugs. 1) The notification bug that sometimes happens when you upgrade 'Knights' to 'Cavalry' where you're informed you have exceeded your 'Horse' supply and units will work less effectively. No matter what you do to change the status of your 'Horse' supply the notification, and the penalty, remains. 2) Once you gain the 'CS gift you Great People' policy, closer for the 'Patronage' policy, some ridiculously powerful GPs are now available to the player. BNW has created the 'Merchant of Venice' that can 'buy off' a CS and it can be annexed/puppeted to your empire. Or if used as a regular Merchant its returns are still greater than a Great Merchant. This is just a suggestion of future intent, not a call for immediate action. I am looking at it but my skills don't match my desires.
