My humans reached level 15 doing a lower level module(if this has anything to do with it, "... Goblin King" specifically), the place where talents are supposed to be seen hinted(visual indication + sound) at the fact that my characters should've received 1 talent, but they haven't.
I think you got your first bronze talent - which transforms a silver talent, rather than getting a new one. A lot of beta testers have complained about this not being transparent - needs a Gary Prompt or something like it to alert the player to what's going on. Check for an item using a bronze talent and unequip it and it'll show up.
It either not updates at the same time my character levels, or I was blind when looking through my equipment. I was expecting the bronze talent to be a new one, not a transformation of a silver one. Also it feels kind of silly how you go from silver to bronze, wouldn't it be the other way around? I only noticed it when I've entered a shop. Thanks for the hint, and sorry for my 2nd miss at bug reporting. I hope there will be some kind of prompt.
Technically it's Clear to Bronze, guys. Silver is the third tier of talents. I agree that there should really be a better prompt when this happens, though. Gary needs to pop his head in and say, "Hey, look, one of your clear circle talents turned into a bronze square talent! This allows you to equip even more powerful items! Over time talents you already have will continue to be upgraded to more valuable ones, just like this."
It would also help highlight the transformation if the talent that was being transformed came up off the character sheet (just enlarged enough to make it noticable, maybe moving towards centre screen to grab attention) then transformed and plopped back down
