If IsPlayerAlive return false on this hack here is something else you can try.

Netprops:
deadflag (type integer) (bits 1), reset it to 0
m_lifeState (type integer) (bits 3), reset it to 1

Also I would check their team index as well. Team index 4 is used in The Passing for Survivor bots. This special team is identical to the Survivor team index 2, except Infected will completely ignore you. However it should not render any Survivor invisible.
Does Commons chase the hacker?

Is the hackers distance still tracked on the score board? Assuming this is Versus, of course.

sorry, I meant I've seen this bug on survivors alive.
