I apologize about the plots constantly resetting. This isn't intentional. Something has been happening when the server restarts that seems to randomly corrupt the Plots world (and occasionally Factions which is also large), resulting in what appears to be a reset. I believe I have fixed it, so this shouldn't happen again. I tried to undo the reset, but it would appear my backup restore isn't working for some reason -.- I'll try an older backup in a moment, and see if that does it.
