All previous battlecrys trigger if you re-load hdt mid game

If you play Mysterious Challenger, end turn, close HDT, open HDT, all the custom battlecrys play.

Maybe this helps: API.Core.Game.GameTime.Time gets you the time (DateTime) of the current log timestamp. You could check for that to be within a certain timeframe to DateTime.Now before playing the sound.

Yeah I planned to do somthing like that. I was just at work and decided to log the known issue so I eventually got to it. Cheers
