Hello,
Thanks for providing some character tools free, especially for new games. I came to the forums to share what I feel is a bug report. It’s my first time on the forums, so hopefully I am dropping this in the right place.
I tuned in to use Starfinder 2e character builder. I found some issues regarding feat selection: I could not take the feat Natural Ambition twice. I could not take the Mystic feat Deity’s Domain twice. As I understand it, I can take these feats twice, because they offer a second choice (a different feat or a different deity, respectively). In other words, the second choice means they are not duplicates.
I am unaware of any restriction in the rules preventing you from taking the same feat twice. Admittedly, that could be foolish, but it is allowed. Moreover, many Pathfinder/Starfinder 2e feats have sub-choices like this, meaning selecting the same feat twice would be a common thing to do.
Have a great one,
Jeremy
