There are two BUGs. The first one is extremely important.

Bug 1: I couldn't complete the "Ascent to Power" mission in the second playthrough of the game ACT2. After failing the first time, the coin disappeared (in the first playthrough, the coin wouldn't disappear until the mission was completed for the first time). I then went to the "Traitors Passage" location and repeatedly killed the mission target multiple times, but the coin no longer dropped. This issue has now prevented me from obtaining new ascension talents.

Bug 2: When I operate with a gamepad, my talent points can be added infinitely, but these points have no actual effect. What's more, when I reset these fake talent points, I need to pay gold coins. The most ridiculous thing is that this situation doesn't occur when I switch to keyboard and mouse operation.
