The originally streamed version of the episode contains what some consider a paradox (under certain time travel rules): Gordon's distress call says that he's been stranded in 2015 for 6 months, and when the final rescue takes place, LaMarr's report on their time jump says Gordon arrived "about a month ago". Both lines of audio (but not LaMarr's mouth) were later altered to avoid the possibility of paradox: the distress call says 3 months, and LaMarr says "four months ago".
