Alright, I just randomly thought about this glitch and now I understand what his solution means. This does not fix the 0 relations glitch. But it can prevent it. Kind of like how a vaccine works. You're supposed to do this when you're at the 1000th-2000th turn or something near that. I guess you can do it later too but I wouldn't take any chances since the bug mostly happens at around 3000-4000 turns.
Anyway, as I said this does not fix the 0 relations glitch but if you keep resetting your turns with this tactic you probably won't be having to deal with this annoying glitch ever because i
