The createActor hook was calling actor.setFlag() immediately, which triggered
updateActor -> prepareData -> prepareEmbeddedDocuments() -> applyActiveEffects().
Since the actor had already gone through data preparation during creation,
the effects had already been applied, causing the 'phase already completed' error.
Solution: Use setTimeout(..., 0) to defer the flag setting until after the
current preparation cycle is complete.
