First of all, I use a server company called PickleHosting, and clients use Multicraft to set up their server. Voltz is being a B****. I select it to run Voltz 1.1.3, and It doesn't start. The console says it will not start a crashed server. I want to run this version because Uranium doesn't naturally spawn in past versions. If I absolutely HAD to run an older version, that would be ok. So I tried that. And the server just stays in refresh, doesn't turn on, and the console says it has crashed. I have no idea what the problem is. Any help is welcome! I also have a YouTube channel, and I am going to do a Voltz let's play once the server is ready. Thanks again. @MilezCraft youtube.com/user/milezcraft

The other day my whole inventory was erased. I had really important stuff and stuff that was really expensive to make. The server owner won't give me my stuff back if I can't prove there is a glitch. So can anybody tell me why this would happen?
