Bug/Issue EoF Error - Multiplayer

I ran into this error:
"Exception caught in client main-loop (EofException) Failed to read full buffer in readFull, eof reached."

in an online game. I now cannot enter the server on that character without immediately receiving that error. I can, however, enter the game as other characters who have already played in the universe and as newly created characters. I was on a Frackin' Universe specific planet, and had just left one of the dungeons.

We are using these mods:
-Frackin' Universe
-Improved Containers
XBawks Character Extender
-Weapon Stats
-Avali(Triage) Rage Mod

My mods and update status all match those of the server (also the only other person who was online at that time).

The log dump is here:
