lol i really dont know if its wrong section
it could sound like a bug for you
and it probably is a bug that it kicks you
but it doesn't kick you
cuz its a matherror
and the chicken is originally not listed in the npc's list
i added it custom
so sometimes there is a matherror cuz i cant so maths like a computer
and he isn't impossible to beat
if it kicks you
ur able to relogin
and then u can continue fighting him with same hp
the chickenhp will also dont be reseted
so u can kill it
but its kinda hard, but thats understandable if u mind that its a 10% chance phatdrop
hope i explained enough now
