Read the side note in the post 
If you are using the Initiative order for ATBTT_GameMode then you will need to include the unit in the Initiative array. I am using my own custom GameMode that does not include Initiative order, rather only by player selection of units and an end turn button to switch to different team turns. (This is mostly because I setup a ‘Hotseat’ type mode that requires you to end turn in order to switch to the other players units.)
Hope this helps!
