Just a reminder for all (and a friendly pointer for those new):

You need to get KOTRfix 1.28a (or whatever the newest version is - usually in my signature) whenever you do something that affects the game (i.e. upload it). Thus when you are fighting battles, being chancellor or taking screenshots for the library, it is imperative that the fix is installed, working, and in use on your end.

The latter two files (buildings&campaign_db) are only needed for the chancellor and those who play battles during AI turns or end the game turn. For the sake of not forgetting about them and having to refight your battle (or have it autoresolved), its advisable to have them in your data folder regardless as they do not harm your game.

If you are unsure whether you got the fix running properly or not or how to use it or have concerns, PM me.
