Server has been running fine until a restart today, at which point it crashes partway through load. I've tried swapping out the modpack to a fresh server and it boots fine, but if I bring in the world file it causes the crash so I'm guessing something is wrong in there but I have no idea how to read and understand these logs, so any advice on what to do next would be helpful, thanks!
