Seasons have been updated. It will now snow in the north during winter (and rivers will freeze) and the banks of many rivers will overflow during the spring.

Winter cold is less-severe than a standard cold-damaging room. It's effects can be mitigated by wearing cloth/leather armor, or by any magical means associated with normal cold.

This is in testing, so please post your comments, or if you find armor that is not appropriately flagged.
