Why would you want mods to help farm? In real life, farming is hard work! They should add a "dig a hole" minigame for each turnip you want to plant! You panzies! ;-)

Another good mod btw is Seed Totem. You can use surtling core and a few other mats to create a totem that you can load up with plantable items. It will then plant stuff accordingly and you can whack it to harvest all ready crops. You can change its radius, or go with a square version.
This is probably the easiest of the bunch since you can Load All seeds and it will crank away indefinitely. As soon as you pick one crop it starts planting in its place.

In any case, we already know the patch is going to mess up any existing explored areas, so anyone far enough along will likely restart anyways and just bring their character and most important loot with them.

Secondly, if the patch breaks the mod (unlikely since its been around a while), you can just remove the mod with no issues.
