I recently went back to the mainland and found that it was much warmer in the Snowland region of Sansara. Could it be possible that global warming is effecting the virtual world too? What am I saying, it's probably just spring! My island just thawed and I'm probably just feeling the contrast from the cold winter and all my snow covered pines, and the green sprouts of the spring weather.
But I do suggest avoiding going down to the garden walk, and wearing your waders if you plan to go fishing... it seems the bottom area has flooded. It's probably just all that melting snow.
