When we checked for cycles with destroy edges around providers, it was only for providers of a different type, but one can do the same thing with the same provider under different local aliases. Check to see if the provider also contains an alias, or is defined absolutely in some other way. The absolute accuracy here isn't critical, since in most cases these edges are not required for correct results, but finding a correct and consistent method for determining when these edges are needed is going to take more research. There was also an oversight fixed here where the basic creator->destroyer edges were added _after_ the cycle checks, limiting their utility. The ordering of the additions was swapped to make sure all cycles are noticed.
