Probably an outdated mod. Just a quick suggestion, put this in front of the mod name: [versionname] modname
[1.6.2] Damage Indicators v22.214.171.124
Very handy to keep your mods organised
I wasn't even using the mods, ModLoader was uninstalled, they were just in the mods folder. Also it hasn't stopped the crashes, they just don't occur as often any more.
