Just leveled up. I heard a noise for unlocking a new talent and also saw the little flash/sparkle animation where the talent would be, but nothing appeared. EDIT: Just went to my keep to check, and I indeed have a new white talent for each of the characters. They just didn't show before.
My fighter just hit 15 and saw the same sparkle, except there is still nothing there when I go to the keep. It's not invisible - I can tell from trying to equip things that I didn't actually gain a talent.
Ah! Thanks Wozarg. All of my dots were in use, so it tried to convert a dot to a square and wasn't expecting there to not be a dot in the bottom left to sparkle. The confusion that followed is now its own bug since mine isn't the OP's. http://www.cardhunter.com/forum/thr...nt-is-messed-if-you-are-full-at-the-time.794/
Lvlled twice to 15 and 16 in a day and both times during the lvl up animation, I see the fireworks indicating new square talent but the talent did not appear under the cutout. Both times two of my items went from clear pip to bronze pip before the lvl up animation. I find it misleading. Either remove the fireworks animation for the talent or change the animation to indicate changing the clear pip to bronze. Then again, some might assume that the item got an upgrade...hmm..
It would probably be well-served by a variety of different animations and sounds, matched with an explanation from Gary (the first time each occurs). I suggested text like:
