Using a spawner “Master” that simply spawns assets and then assigns them an array.
Using a tripbox “Tripballs” that simply activates the physics of the array.
Using a physics object “Balls” that simply holds a sphere with no physics.
To create the bug follow the Youtube video below and then follow the steps.
Not sure what is causing this, I printed the array length and all of them including the last duplicate holds the same array value. So not sure why all are being called on the last duplicated trap. I tried clearing the array on begin play as well thinking that it was merging them all into one group.
Note: You can avoid the bug by not using duplication with holding alt and drag. But then whats the point of having the ability to duplicate objects with arrays?
