does the mod change according to the level ingame and will this make my computer lag or nah
Nah, the mod is client side, we have no power over how your client side mods work. You'll have to change the level yourself via Ctrl + Num+.
For those who skimmed through the thread because they've already read it last year (hey don't blame me, it's still up to date), there has been a small change/addition - there will be a /snowlevel command added that any player will be able to use at any time to check the current snow level. It will be updated together with the MOTD by administrators along with the weather-changing asays.
