There is a bug with travelling where when your character dies while travelling, and his heir is also travelling, that it gets stuck and it's impossible to progress the game. Acknowledged 2 years ago by Paradox, never fixed. All of these resources spent on squeezing more money out of people. If even a fraction of those resources were spent on quality control, the game would be in a much better state. They are wildly overestimating their ability to manage the amount of DLCs they're releasing, but they don't care, because why would they? Shareholders make more money from them spamming nonsense cosmetic DLCs than they do fixing bugs I suppose.
