Implement a better fix for not being able to modify a tree

Sometimes a node can't be modified in the anticipated way. Right now, it just bails on that node. But, we have a list of all possible nodes we could modify.

- [ ] Instead of just bailing on the given node, write a while loop that exhausts all possible `paths_nodes` before giving up. (See `buggers.py.module_not_found_bugger()`)
