the current Plot#getOwners#contains takes server-plots into account (so, if the server uuid is passed into this filter, and a plot is server owned, this filter would return true). Plot#isOwner uses Plot#getOwnerAbs and therefor would not produce the same result. Haven't seen an occurrence of a server plot being queried - not sure if this should just be changed either tbh
