Hi Civinator,
I had some free time to test a few things, and I started a new game.
But something must be changed.
If the button for escorting the supplyshipments is not appearing any longer, may be you have disabled the option 'Show advanced unit action buttons' in the Preferences setting of your game.
No, I didn't change anything and the 'Advanced unit actions buttons' option was enabled. The only thing that I did was to generate a start in the Editor, and assign one of the existing starting locations to the civ I was playing.
However, I found a way to fix the supply shipments issue:
In the Editor, I deselected the ‘Default Game Rules’ and then selected manually the following options: a) Capture the Unit, b) Reverse capture the flag, c) Victory Point Scoring.
Then started the new game and the 'capture shipments' button was there. The only problem was that the Scientific Leaders was disabled in my game, as expected (no way to enable that if you deselect the ‘Default Game Rules’ in the Editor).
Now in my game I am in the Industrial Ages, and I have not encountered a single bug yet

. I noticed the new content and units (I really like the Diplomatic option), and CCM2 is looking great so far

.
A few things that I noticed in the last version:
- In Civilopedia, USA are still listed as Scientific & IND, but they are Expansionist & IND.
- Heavy Archers and Longbowmen have Zone of Control. You could add that in the Civilopedia description.
- Medieval Naval Explorers do not have bombardment (the Civilopedia description is wrong).
- I noticed that the AI civs do not send their units who carry a supply shipment (red coloured units) to their capital. Instead they leave them fortified out of cities, or even send them to war with the supply shipment.
- I think it would be better to list under Luxuries only the luxury resources in CCM2. Although it is stated in their description if they are luxuries or not, it took me some time to understand why some of them do not add to happiness
