I have a simple AI setup for moving to a player and then attacking once they have reached them. However the sequence node that leads into those nodes is skipping the attack one. ![266365-unrealbug.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/f/5/3/f534eb525d03ab3c599935d5e1207a95b87fd14c.png) And this is a gif of the behavior: ![266366-unrealai.gif](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/f/b/bfbd460ebac5c98d5c45ea08de1eac82931f41ea.gif) (sorry for the jumpy gif, its really fast switching) Why is it not going to the second sequence node? (EDIT: I have deleted the nodes, remade them, remade the Attack file, broke all the links, didn’t work) ---

Hi Aedan, It would appear that your first sub-sequence is failing for some reason. If that happens, the second sub-sequence will not fire.
