Because the game LIES by having the Trade Route rollover say "Total number of turns to complete this route" when actually that's only the minimum tile distance between the two cities, I've been using the Better Trade Screen Mod. However, I've noticed that my turns to completion have been going negative. It appears the trader is taking AN EXTRA TRIP than I expect. My experience was if one round-trip took more than 20 turns, then the trader would make just one round trip. I have two trade routes. The minimum tile distance between the two cities for both trade routes is 11 tiles. The actual tile paths (road) for the two routes are 12 and 13 tiles. So I expect them to complete in 24 and 26 turns. Instead, the trader keeps going! Was something changed in the Sept update to make trade routes longer? The only Mods I'm using are UI Mods (like Better Reports). I even tried removing Better Trade Screen right before a trade route should have finished. It didn't. I play at Deity level, standard speed. Oh, and both the mentioned trade routes are international. Save game available upon request.
