Hello! In the past few days, one of my servers has been refusing to start. I've been working on some maps on it for a couple weeks, but all of a sudden it won't start, no matter what I do. I've checked the forums, repaired the files, and restarted it countless times, but it still gets stuck on the 'starting' phase. Whenever I start it, it does log as 'server was online' but I am unable to join. Any ideas on how to fix this without completely resetting the server? Any help is appreciated!
