no-one reads this anyways
k,bye.

so, winter and spring are kind of implemented. not fully done. Also a bunch of bug fixes and things.

Points are working, rooftops are clipped off, pickups were added and everything is good.

Just now realized the file name is cp_seasons_a.bsp so that will also be fixed
