Help with multiple AI Enemys

Hi guys, I’ve been working on a game like Dungeon Defender, i can spawn “X” number of AI bots and move them to their respective goals, but i have problems to align them when they found their objetives, for example when i play start game if i wanna spawn 3 AI bot, spawn in this sequence:

AI3 -> AI2 -> AI1, forming a row then they move to the same goal (gate) in the same line and only the first one AI Bot spawned attack to the gate, the others are stuck .

And i want to aling in this sequence when they get the goal:

AI3

|

AI1

|

AI2

Actually i’m using “AI Move To”, then On Fail Ex i use “Set Actor Location” with an offset, but i dont like the results, anyone has an idea?
