There currently is a Bug when you try to grab the tree the frame it hits the ground. The state of Padoru gets updated to having grabbed something, but the tree is already marked for destruction, so it dissapears the next frame.

This allows the player to "throw" projectile that aren't actually held.

Simple way to reproduce:

1. Enter trainings mode
   
2. Place tree
   
3. Enable frame advance
   
4. Use uptilt
   
5. Forward 53 Frames
   
6. Press NSpecial
   
7. Continue

Now the present or tree can be thrown remotely.

This can be fixed by adding an additional check in the code responsible for grabbing the
present, on whether the Tree is marked for destruction.

However, this bug opens some intersting gameplay opportunities, so it should be considered to replace the Bug with a similiar intentional mechanic that doesn't require a frame-perfect input.
