Problem Loading Maps

[Duddha]

In my modded game by adding city improvements and new units with the hacked editor. After the change I can no longer play on custom maps, even ones without their own rules set. I thought I'd ask if anyone knew why this is happening. This is the error message that comes up after I load a map.

sounds like these custom maps were made under a different patch, so the bics aren't compatible
