Indeed, therefore it is best to keep the number of real changes limited. Here are the Civilopedia entries for the 2 new units btw (the Alfa might be associated with an different tech):
95.41KB
108.22KB
And the units in action:
39.46KB
Details of planned unit producing small wonders:
152.95KB
That's quite a lot and finding / editing a full set of graphs for each of them is a hell of a job, instead I'll make a Civilopedia entrance for each of them and some standard graphs for the Civilopedia, City screen and Splash screen.
