Hey there
You’re teleporting the item you detach from the player to the root of the item you’re attaching to the player, so it will be on the way when the player tries to move if it has collisions. If you don’t want that item anymore you can just Destroy Actor.
Also, the item you attach can block the player if it has collisions as well and it gets in the middle of the capsule.
If you don’t want to destroy the items, you can make them have no collisions that affects the player, only the channel for your Line Trace, in this case Visibility. Then you can change the collisions on Pick Up.
