Party bug hotfix

The load function will now reset your puppets to the default party if you somehow manage to get more than 3 puppets in your active party. (They will be unequipped first, so don't worry about losing anything.) You will also now be prevented from doing anything if you exceed the party size limit.

I am currently working on how to fix the bug that enables you to add additional puppets to the party. If it happens to you, please document exactly what you did and add it in a comment so I can figure out what's causing this.
