Hello, you can operate on pawns to replace hands and foots with a peg and then replace the peg limb with a natural limb. This process will not cause a mood change but will use more medicines and have a greater chance to fail since there is two operations however.

Another problem with that is in replacing the limb with a peg, you'll get the natural part also. This same limb can then be reinstalled without fingers or toes missing. I've talked a bit about this in the description of the mod in the "Known Issues" part.

But what you can do is mod the mod!
In the mod files I've voluntarily let fingers and toes texts in commentary. You just have to uncomment those parts. If you or someone else are still interested I can explain the process to do this. Just respond in comment.

Also, the reason there is no fingers or toes harvestable in the first place is that it will add twenty new items to harvest in the bill list and I think it's more readable without.
