The two mods mentioned in the title have a conflict with the tomatoes added in the two mods. Both kinds of seeds grow and only drop Sandwichable tomatoes. This would not be an issue however you can't use the tomatoes in Sandwichable to craft any of the items for Croptopia, making it not impossible but very impractical to get Croptopia tomatoes. The only way to get them currently is to plant the croptopia seed, then immediately break the crop, dropping a Croptopia tomato. This is very inefficient and adding a way to either convert the tomatoes or make both drop their respective tomatoes would help the mod for the better.

Disregard, I don't know how I had this problem but it is no longer an issue.
