Description

When you open the network tool (by right clicking), right at the same moment
when you take damage from a mob/player, the client crashes

Environment

I first discovered this on a MP server with a bunch of other mods when a player did damage to me.
So i tried it in SP, removed every other mod and updated both forge (12.18.3.2281) and ae2 (rv4-alpha-11),
spawned in a zombie and a witch, the client did crash when i got hit by a zombie and at the same time as i right clicked the network tool, however it did not occur when i got hit by the witch (poison damage included), probably because it's some other kind of damage.
