You can't shackle a creature that is already shackled. So, it's not a bug

The question about automaton, yes, it's a known bug. I hope they fix it in the next week patch

2 questions about interactions that I’m not sure are bugs or not. 

First dropped sun in shadow with my other 2 creatures temporarily shackled and it wouldn’t let me permanently shackle them over top of it. It was like my 2nd time ever playing the card so I’m not sure how it is intended to play out. 

Second reflective automaton didn’t trigger guar stablemaster. If it has all types shouldn’t it trigger the beast type?
