So I didn't think to take screenshots of this. I was exploring and came across a Boar and a Halloween Event Dude (the boss guy I think 400HP - Gywnn or something).

My wolf was unable to do any damage before Event guy killed them. I healed and went back to explore to have another go and they've both disappeared from explore.

Is this normal? I know normal predators must be killed to count, but does the event allow them to flee when my wolf flees since they don't count towards my overall predator count?

I've never had this happen, my other account is higher in explore and I can go back multiple times to try and win against a slueth of bears, never had them flee unless during the battle.
