Thanks for the suggestion, but I’m not actively playing the game at the moment. I’m only maintaining my mods.
I have to admit that without having use LTN, I can’t figure out why that condition is necessary. If the mod generates a new refuel condition every time the train returns to the depot, can’t it generate a condition to send the train to the station that matches the fuel currently inside the train? Instead, it sounds like the mod generates a bunch of conditions to match all kinds of different fuels.
I guess the problem is that whether or not the fuel condition generation is designed well, now all mod users expect the mod to behave like that and it’s unlikely to be changed. Instead, all other mods have to work around their questionable decisions. :(
