So I run servers for me and my friend to play on. I've played minecraft for a long time with mods, and haven't ever had this come up. I've asked a lot of people who usually know how to fix errors like this how to fix it, and no one has been able to help me thus far. So, here's to hoping one of you can.

I'm going to give a link to all the images I have for the crash. This includes the crash in the window that opens from the .bat file, the mods I use, and the text that appears in Minecraft when it rejects us joining the server.

And here is the crash log:

I've been told that deleting the map and generating a new one might fix it but I want to know if there's anyway to fix this without losing our map because this happens every time we stop playing and try to get back on it at a later point in time. On top of this, we have a creative map we've been working on for a very long time and I would be devastated to lose it. I know that I can make back ups for the creative server but I just sort of don't want to touch it at all until this issue is resolved because we won't be able to make any progress on it if I have to go to the back up every time.

Anyways, if you need any additional information just let me know either on here or in a message to me and I'll be happy to provide it.
