Not an errata as such, more an observation and query. I notice that Plasmavores have been given the Shapeshift trait, and this is also described in the text. So far as I recall, the Plasmavore in Smith & Jones was able to alter her DNA after drinking blood, to resemble that of her victim. But I don't remember anything about her being able to shapeshift her external appearance. So, is the entry in Aliens & Creatures an expansion on what we know, or am I forgetting something from the episode? Even if it's the former, it's not really an error as it doesn't contradict anything from the series - I'm just curious.
