1 and 2 are actually the same answer funnily enough.
The capsule component is NOT your character. It’s what’s used for movement collision. You can turn it visible during the game (in your character blueprint, select the capsule component in the viewport and under rendering untick “hide during play”.
You can see it’s around your character but it’s a bit beyond it.
3 is a bit different. I’m not too familiar with the homing component and couldn’t tell if it has something to do with that component itself. But is your “Replicate Movement” box ticked?
