Tip: Reloading conquest categories
It's possible that this is a known "exploit," but it turns out that you can change what type of conquest you get. E.g., Veronica asks you to pick what type of challenge -- you pick "number of items sold." She says ok, face off with number of winter crops sold. You don't want to do that, so you rethink it and press B. Pick number of items sold again and it should change. This way, you should always be able to go by total number of all items sold, which is useful if you hoard fodder for conquests wins.
