So I was making a zombie farm with a few friends, and we started it and got part of the barn done, and my server crashed for no reason at all. I had saved, luckily, and reloaded it. Then we make pretty goo progress, and my server crashes again, for no reason at all. I hadn't saved it again at that point, and lost all motivation to finish the build.
Does this ever happen to you? I find it to be the only thing that can deter me from finishing a build, besides the lack of an event or something, but that's different.
