Okay, here are the things that I currently have pending before I would like to post a release:
- Permanent war/peace problem only for specific civs.
- Combat units located in city states at startup are being relocated (this seems however only true for non-human players).
- How to modify the value of a unit so that it improves relationship a lot when given as a gift (I've already given the unit a high production cost, does this increase the value already?). I had a quick look at that City States Diplomacy mod but it looks like a complete re-write and I'm not yet that familiar with modding.
- When a unit is captured it loses its unique name.
