Spoilers follow, of course.



Putting the 970 crashes and numerous bugs aside, things that disappoint me are world inconsistencies.



Listening to the woman in the village keep talking about her husband going back to see the witch long after you've killed her.



Raising the buried botchling in its guardian form the people of the keep were supposed to all be shut indoors. Not only are there soldiers and others outside while you do this, not a single one of them took any notice about you following this ugly glowing spiritual creature through the keep.



People who have already met you and know who you are keep saying "You're a witcher aren't ye?" As you pass them by. This is ultimately strange when Jutta says it to you not long after you just got done bedding her. Also along these lines are people you just helped and then if bump them accidentally suddenly they yell at you about how you have no respect for their ways and customs.



I find it amazing that almost every single monster has advanced combat tactical training where they know how to dodge and fight just like I do. Even mindless animal can dodge with the best of them. Most of their combat tactics are all the same too.



Not being able to get rid of quests in my quest log. I really have no interest in any of the Gwent missions yet there they are, forever intermingled with all of the quest I am interested in doing.



Those are but a few, but the ones that bug me the most.
