Luxury Resources Glitchiness

[Callow]

Hey guys. Lately I've been noticing some issues with luxury resources in a few different instances.

One is that the game seems to have trouble tracking how many luxury resources I have. For example, sometimes I have access to trading away three Ivory and one Gold to Sweden, but no luxury resources at all to Byzantium.

Other times, I'll trade away one resource that I have multiples of, and then find in later trades it says I have no more duplicates (like I traded away my one copy of that resource).

Can anyone tell me if there are certain mechanical instances where any of this could occur, as in explanations for why this wouldn't be a glitch? I've had errors occur like I explained both in single player and multiplayer games, and I'm just at a bit of a loss as to why I can't trade away luxury resources in a lot of cases. The cities that have the resources are always connected to my capitol via a trade route; does it matter if they're connected via harbor or road?

Thanks for any help. ^^

yes this is a bug. I guess you just have to be more careful or just cancel the deal and renew it yourself when your turn come.

Don't now about the rest... but this is due to Byzantium not needing your resources, as they already have them from elsewhere.
