So this BP was working perfectly fine before I upgraded from 4.16 to 4.17. What it does is that this giant growing translucent shape, when overlapped with the player, it follows the player around with the Tinterp To node.
Now that I have upgraded to 4.17, it still works for the most part, but now the actor that follows me has jittery movement. In version 4.16, the actor’s movement was perfectly smooth.
Here is a video of what I mean. After the shape is finished growing, you will see that it will shake and jitter:
