Since the script for fairy recruitment seems to work properly now, having four sequentially upgradable versions of the fairy spring for all season now seriously hampers the fairies as you can not produce any of the seasonal units before the next year. One turn for first level spring + 2(8) for the next level spring(s) means you are always behind the seasonal change until the second year.

I propose simply removing the seasonal buildings and just having an upgraded fairy spring that allows for the recruitment with seasonal variation. Combining them all into one building shouldn't be too much of an issue as the Great Fairy spring can just be made more expensive and it's buildtime increased to prevent Great Fairy rush if that is the reason they are left in.

Well, this in this part of the forum now but someone move it somewhere useful
