I have had Minecraft since it first went to beta in December of 2010. I play SSP(single player) about 99% of the time, all of my submissions come only from me and most of them are located on the same map - the one available for download on my
Selkirk Metatropolis post.
The map itself is old and contains sections that predate the adventure update (when creative mode was added) which may be the reason it sometimes ices over when it gets downloaded. For this I can only apologize and hope that you will forgive my insistence on retaining the old landscape.
My PMC handle is pronounced 'candy raver six-oh-four' just to clear up any confusion.
