Explode at index bug

Hi David Stasiuk,

I've been happily using your Treesloth components for a while now and it helped me a lot when editing complex data trees. Thanks for that!

One of those components is the 'Explode at Index' component. However I've encountered a bug in this one. It seems that the last branch is always absent, when exploding. Are you familiar with this and do you perhaps have a solution?

Thanks in advance.

Gerran
