I fucked up my world in Minecraft. I was working on this giant project - a huge, floating palace in the sky, and I destroyed it accidentally. I have easily put 40 hours or so into working on it (and I'm being VERY conservative with that estimate, it could possibly be double or even triple that amount of time, as anyone who's played this game can attest at how 10 hours of playing only feels like 1), and I wasn't anywhere close to being finished. Now a large percentage of my work is permanently destroyed thanks to chunk errors.
I have 3 computers, two of which run Minecraft. On both computers which I play Minecraft on, I dual-boot Windows and Arch Linux. In an attempt to make it easier on myself to move saves between computers, I linked my saves folder to a saves folder in my Dropbox folder, which should sync my Minecraft saves to dropbox and furthermore to all computers and both operating systems. This is good because I primarily played on that one world anyway.
Somehow, something went wrong. I'm not sure what, but when I loaded my game on a different PC, there was chunk errors everywhere, which the level generator filled in with random stuff. That wouldn't bother me so much if it was just in random places in the environment, or even in my old structures I've built (though I would miss them a bit). It's the fact that it took hours and hours of work out of the biggest project I've undertaken yet, which I've spent the last several months playing Minecraft doing, and erasing about three-fifths of that work. I swear I almost feel like crying right now, after losing so much time and work.
I made a backup a day ago. This would mean having to rebuild a couple of rooms and redecorate a couple of areas, sure, but it's maybe an hour or two of work. But I can't find anywhere on my hard drive. It's seemingly just dissapeared.
I no longer have the motivation to play after losing so much now. Sure, a month from now or maybe even just a week I'll probably start a new world and get addicted again, maybe even starting a new megaproject... but for now I'm just too upset to play the game.
