This question has probably been asked and answered but after going through several threads I can't find the answer. I've read in several places that if you expand your map beyond your research the battles will get tougher than they would be if you had stayed even with the research. I do don't battles, only catering. Right now I'm just starting chapter IV but have already expanded to 69/70 provinces for the chapter V adv. scout chest. I've been holding off on expanding more because I don't want higher catering costs. Will my catering costs increase if I continue to expand before getting to the adv. scout chest for the next chapter?
