(possible bug?) Nettles checking for a season that doesnt exist

this is the code within the nettle_plant.lua

the error here is that it's looking for winter in a hamlet world, which doesn't exist. and I havent seen anything in the season manager .lua file that points out that winter can be a different season depending if the world was using hamlet's worldgen.lua or not, thus making that nettles can only grow if wet.
