Ped Scenarios

I'm trying to use Ped Scenarios for a callout but I've come across a few issues.

1) After the scenario has been used once, it won't play if the call is taken again. It only starts working again after I restart the game.

2) I'm unable to get more than one ped to use the same scenario at the same time.

I've looked at the natives surrounding scenarios and found a few that might imply you cannot use the same scenario on more than one ped at the same time. "IS_SCENARIO_OCCUPIED" being one of those. I also found "RESET_SCENARIO_GROUPS_ENABLED" which makes me think I may have to 'reset' the scenario after I'm done using it to be able to re-use it again.

I'm not sure about any of this, I'm just trying to figure out why these issues exist. If anyone can confirm this or give me an idea of how I can troubleshoot this, please do.

Thanks.
