[Scripting Question] Wrong season deerling spawning

[Heracross719]

I'm running 18.1 and i have a forest which changes based on the season... so obviously deerling will be there.

It's October which means Summer and the map is showing me summer but when I get into an encounter with deerling it's showing up as the Autumn one. Any idea what may be wrong? Below are my code for seasons and deerling forms. I already checked and the sprites are correct. regular is spring _1, _2, and _3 are Spring Autumn and Winter as they should be.

# Seasons

def pbGetSeason
  return (pbGetTimeNow.mon-1)%4
end

def pbIsSeason(seasonVariable,*arg)
  thisseason = pbGetSeason
  ret = false
  for wd in arg
    ret = true if wd==thisseason
  end
  if seasonVariable>0
    $game_variables[seasonVariable] = [
       _INTL("Spring"),
       _INTL("Summer"),
       _INTL("Autumn"),
       _INTL("Winter")][thisseason]
    $game_map.need_refresh = true if $game_map
  end
  return ret
end

def pbIsSpring; return pbIsSeason(0,0); end # Jan, May, Sep
def pbIsSummer; return pbIsSeason(0,1); end # Feb, Jun, Oct
def pbIsAutumn; return pbIsSeason(0,2); end # Mar, Jul, Nov
def pbIsFall; return pbIsAutumn; end
def pbIsWinter; return pbIsSeason(0,3); end # Apr, Aug, Dec

def pbGetSeasonName(season)
  return [_INTL("Spring"),
          _INTL("Summer"),
          _INTL("Autumn"),
          _INTL("Winter")][season]
end

MultipleForms.register(:DEERLING,{
  "getForm" => proc { |pkmn|
    next pbGetSeason
  }
})
