Hello. For starters, I have a very impressive singleplayer world in which I am attempting to recreate every major town/structure in ME. So far, I am 18.62 days in ( about a yr of building irl). I've built locations like Barad Dur, Minas Tirith, Amon Sul, Minas Morgul, the Argonath, Imladris, the Morannon, Cirith Ungol, Orthanc and Osgiliath (WIP). Obviously, I use a lot of worldedit. Yesterday, when I was working on a model for the tower at the Hornburg, my worldedit all of a sudden stopped responding. However, I could still manually place blocks and fly around. Its just very annoying, because all of my builds are gigantic in scale. Upon further investigation, I realized I could no longer type commands, fast travel or anything else, really. In all other worlds, though, everything is running fine.I've looked around the internet and some sources say that maybe my world is just too much for my computer to handle. I don't know how to fix this, if it can be fixed. I do have a world backup from Jan 5, but I don't want to lose a wk's worth of building. Any advive? Any help is rly appreciated.
