Beta Version 0.81

http://newvegas.nexusmods.com/mods/46907

Just added a new update file (v0.81) which fixes and improves the weather/sky/fog. It fixes the issue of black clouds sometimes appearing. If you already downloaded the 0.8 version, then you only need the esm file from this archive. If in doubt, just extract everything from the update and overwrite when it asks.
