This issue is a bit more difficult than it first appears.
Ideally now when you create a link, forces delete properly. However, when you add a force on a link, and weld it, the force is on the subset but not on the compound link. The force from the subset needs to be also added on the compound link as well but still fix the force to only the desired subset.
Also, a check needs to be done where when you add a force on a compound link and you delete the force, the force needs to be deleted.
