I got a bug,made my character immortal..

at cycle 40,my base got some problem,my 13 vitals died one by one.but at cycle 60 the last one who survived now got immortal...

strave,poison gas,cold,none of these can kill my Mr.Long.

and now,cycle reached 900,but this immortal Mr.Long still survived

here is my save file. 

sorry to my poor english,im chinese
