Bugs I've noticed:
From 1.0 - Quest Dirty Funds stalls if you clear the target area before reading the note.
From 1.0 - Puppet (Axii mind control) does not work if multiple Axii skills are equipped.
Old - Hard Times quest, NPC you are supposed to turn the quest into will not talk to me. I am unsure if this is just a random error for me or if it is a common problem.
New, PC only? - Significant increase in stuttering with this patch.
New - Running away from a combat situation causes the combat music to get stuck on. This overrides all music changes, such as playing Gwent, and persists through loading a savegame.
New, PC only - Default gamma is extremely washed out, to the point of losing color information, resulting in color banding. Using the game's gamma slider to fix the washed out appearance makes the color banding even worse. Strangely I've seen one person claim the opposite, that the default gamma is extremely dark.
