RPG Combat System with World Map Mode and Turn Based Mode Switching

See this is what I was playing around with before but since the persistent level is still loaded it doesn’t really change anything, I still need to pause of the AI functions etc since essentially I am doing is moving the player and the enemy he has ran into to a separate area of the map, since the streamed level still has to appear as a portion of the persistent level it’s really just like me having a room in the persistent level, picking up the player and monster he is fighting and changing their world location to be in that room, everything thats happening in the main level is still happening.

Any suggestions on a global “pause” function to stop the behavior tree on the other characters from continuing and stopping other functionality outside of the current streamed level?
