Suggested correction: This series is not meant to be taken in exact chronological order. Most episodes have no dates or time of the year set. Unless we have reference to a date or time period of the year; we have no way of knowing if the continuity is truly off as this series is meant for the episodes to be taken within a generalized time. Not in any specific chronology except for a few where the time period is specific. Neither this episode or the one before it has reference to a date in time.
Suggested correction: While the other correction is wrong, the real reason this isn't a mistake is because the episodes were aired out of order they were produced, which means it's not a mistake within the context of the show. "Bend It Like Baxter" (production code 315) was filmed before the previous episode, "Double Vision" (production code 318).
