On my computer I have discovered a 2 month old version of my world. this is a version before i knew where i wanted to build my newest creations. so several sky islands i blew up are still there, the harbor had not been hollowed out, my 3 towers were not there. It was a sureal experience. like going a few months back in time. so i have decided to find good viewing locations and take before and after pics. they should be pretty interesting to see. check back soon for those.
