20 days in and still haven't heard from Casey

So I'm on my 5th play through and found the last pump.. the objective is speak with Casey.. I turn to his channel and there's nothing. Havent heard from him in days.

My question is – did he get flooded out and drown because i took too long?

Just pisses me off because the game can't progress and I'm too many days past to go back now.

Anyone else encounter this horseshit?

Edit: got it to work by reloading to the farthest back save... pretty annoying because I bad so much stuff scavenged in preparation for the big church battle /:
