it doesnt do it all the time... so atm no way on players end to find a defining moment. it not only makes copies of other ppl without their armor, it also negates spell effects. when you cast spells or have spells cast on you, you can not see them (i always have spell effects on and yes i checked it was still on
). when i ran with insane last night he actually was killed during a keep. i clicked on my group window to rez him and it showed him full health, not allowing me to cast rez. another player arrived so i also invited venomous, when i did so he wasnt getting the invites to group.
so it does appear to actually be affecting more than just spell effects and making all these crazy paper doll copies.
