As of r75274, patrol tokens accepted by action=patrol and generated by list=recentchanges are no longer equal to edit tokens and are no longer the same within a session. Instead, they are now different for every recentchanges row (i.e. they depend on the rcid). It may take a while for this change to be deployed to the Wikimedia cluster, but in the meantime changing your clients to no longer depend on the patrol token to stay the same can't hurt.
