Internal server error in TF

[007Nick700]

So I was playing with some friends and I went to the twilight forest. From one moment to another I just got an internal server error and got kicked from the server. Yet, my friends said my character was still in the world and on the player list. One of them teleported to me and got the same thing. After a while a thrid one tried and got it aswell.
The result, the 3 of us both get an internal server error when trying to log on. The Twilight forest has been resey already, our .dat files have been deleted and the server has been restarted numerous times. We have ran out of ideas on how to possibly fix it. Any help is welcome.

Tried to set up a new local server and when I fired it up, it crashed throwing the exact same exception about n not being positive.

your server is borked from the Twforest mod. Make sure that mystcraft worlds are not conflicting with TWF.

Even though your client crashes on load. Your steve is still on the server. As soon as you login, hop into the server command console and type in /tpx <name> 0. this will tp you out of that world and take you back to overworld. re-log, and you should be free. Do the same to other trapped players till everyone is free.

Do you by any chance see some World Leaking messages after the server starts?

Does the crash happen after trying to place some chunk loading block?
