I'm having a problem that is probably by design in one of these mods. I'm using basically FCOM and Better Cities and All Natural, with a leveling mod and that's about all.

Anyway what's happening is when I sell to a merchant his gold available goes down like in Morrowind and never replenishes. At least I've waited a week at Ongar the World-Weary and he's never replenished his gold. This makes it impossible to advance in the Thief's guild as far as I can tell, which is why I'm writing here.

Have a look please, and see if you can help me figure out which mod is doing this. (Load order by BOSS)

You have quite surely installed Living Economy as part of your Frans installation. I think you will have to wait somewhere else than close to Ongar, so that the cell can be reset for Living Economy to replenish his gold.

If you want to remove this feature, the simplest is to reinstall Frans, this time making sure not to choose LE. Another alternative, if you like more immersive merchants, is to install my http://www.tesnexus.com/downloads/file.php?id=25078 mod. It does pretty much all LE does and much more, all configurable in an ini file. For the specific case of replenishing merchant gold, EE behaves much more immersive, and you will there notice that the merchant receives back some gold during the day (you must just be away for at least 2 hours) due to trading with other customers.

If you install Enhanced Economy, it will detect that you have LE installed as part of Frans and ask you if you want to disable LE, and it will then do it for you.

Your mod solved the gold problem nicely. However, the merchant buy values are aggressively low, how can I configure that so it's a little higher?

Read the readme and configurable INI file for Enhanced Economy. You can make it tough or forgiving - whatever your preference.
