Anyway, very timely for this to happen while another project known to be in a bumpy production is in the news for having "all episodes finished". Don't take this to mean that the job is done because it very much isn't

You gotta have something to deliver even if you know it needs retakes, so having not-really-finished-but-itll-do masters is common. Depending on the platform's needs (a service that needs to tl & even dub will demand materials way earlier than a TV station), those can vary a lot even for final video
