I have player of my World of Dragons modpack that is crashing when they try to get on. It's rather unique too as it doesn't generate a crash report.

Looks like you started doing something sponge mixins. My server is pure Forge. no sponge at all.

start at line 465

I think we can close this. The player had a corrupt install of the pack, they reinstalled and the problem went away.

Good to hear that.

EDIT sorry wrong button :D

Looks like it's an issue with another mod, but I can't figure out which one. Can you try and find out which is causing this problem (just remove them and see if it still crashes)?
Maybe try to remove laggoggles first.
