In such broken or-groups he now tries to install a non-installed non-deleted member of the or-group to statisfy it again. This move is dangerous as it introduces the possibility of a bunch of "new" broken breaks/conflicts on the new statisfier or its dependencies and we don't know about them beforehand. We also don't have the infrastructure to undo the decision later, so we just do it and pray!
