Well I finally decided to get rid of the snow and download the new heRO mini installer, updated everything and the snow was gone!! However with the snow went the blue rabbit ears, which is now an "unknown item" in my inventory. I can equip it, other people can see it, but I can't.
So I ran the hero patcher, and the blue rabbit ears returned to its normal state, but the snow is back!
Would someone tell me how to get rid of the snow without affecting any of my items?
