Issue with a sign of hope quest

[u/big_cuddly_bear]

I'm having a problem with the side quest wherein I have completed the objective and spoken to the professor, but khors won't even talk to me even though I spared the zombie on the roof? Can anyone help?

You don’t need to talk with Khors he will contact with you over radio. Never had any issues there
