When I try to change Linear Position Drive properties during runtime, they have no effect on my scene.
Details
I have two actors that I am constraining with a Linear Position Drive. One of the actors is set to kinematic while the other is dynamic.
If I use the following constraint settings and hit play, the 2nd actor is pushed away as expected.
Now, trying to do this in runtime, I set position target to zero and change nothing else.
I then add the following to my level blueprint.
When I start the game and press F, nothing happens. If I pause the scene and look at my constraint actor, I can see that the Linear Position Target has correctly been updated to -50, 0, 0.
