Are you changing the values in Unit_Parent, the different unit blueprints (Unit_Player_Melee etc.) or in the individual units? Either way I’m not able to replicate this bug. Does it happen at once or when you close/re-open the editor?
Here is a pastebin of my solution: http://blueprintue.com/view/tfYSQvQa/. I modified it a bit more so that the current units turn will end automatically if there are no enemies in range after it has moved. Just replace the “Begin Unit Turn” stuff in ATBTT_PlayerController with the stuff in the pastebin.
