Another thing to add:
You should only use sequence if you are plugging in executions that don’t rely on or need to wait for anything in other attached execution flows. If Then 1 needs a result from something out of Then 0, you shouldn’t have a Then 1; all of that code should be on the end of Then 0. And if you only have a single Then node, just delete the sequence node altogether. Each node adds to your start-up memory when you play the game.
