I might have done something wrong, but it happened more than once where I would change a few things, look at a different map, then go back to the previous map, and the changes would be undone. I would sometimes save each map while I was on it, then come back to it, and it would still be undone. The changes seemed to stick sometimes but others not, maybe it is that I have to exit the map in a certain way for the changes to be saved?
Another thing is that when I go to another tab other than civ iv such as a screenshot, the world builder settings will change from whatever I'm editing, say, Charlemagne's City Name Map, to Justinian's Unit Placement (as always, I know that's normal). The map on the screen however, sometimes continues to show the Charlemagne labels, but if I go back to the city name map editing, it gives me both the French and Byzantine landmarks on the same page. Then when I leave that screen, it updates, and next time I try to open Justinian's city name maps, it is Byzantine mixed with French.
I've found out ways to get around this, such as switching to Charlemagne in the unit placement THEN going to city name maps, and that gives the appropriate map without any errors, but if I ever accidentally do this in the wrong order, I have to start over. I also figured out that saving the changes works most usually when you switch from one city name map to the other, THEN go to another part of world builder, regardless of when you actually save the the map through the menu.
Also, even if different names get saved on land tiles, when I remove names from a water tile, they always come back, it seems that city names can only be changed and not removed? Please point out my error if I'm doing something totally wrong.
This editor works, essentially, and I managed to edit all the provinces, settler/war maps without issue but I would personally rather do extensive changes on city name maps such as those that are necessary with the new Iberia in a way that is less "risky" (that might just be my fault, this feature is still extremely useful). If I need another map for reference I just pull up a screenshot I make or something.
