In TD12800, consistently the Replicator COMP doesn’t run its onReplicate callback when incremental update is set 1, and sometimes it doesn’t fire them when set to other values in a non-deterministic fashion I can’t figure out.
Additionally it appears that the Replicator doesn’t create all the objects expected based on the template when Incremental Update is on (in my case it’s creating 2 out of about 33), but when Incremental Update is off and nothing else is changed it creates all the objects specified.
