1. White Orchard. South/west/Near windmill marker. There is a small barn with a second story window and a hill. You can jump into it, land 2f rafter/alcove, drop down and due to lock never be able to leave

2.White orchard Main quest beast. If you discovered the nest prior you miss out on a dog killing trip with that woodsmen. If you picked up herbs dialogue with herbal girl. Not sure if a bug but needlessly punishing and wouldn't pick up glowing stuff underwater knowing its sure to be diagrams

3.. Southwest Velen. Shore side,near flag named shipwreck. There are 4 or 5 big half sunk sinks, 3 or 4 upside down ships. On the big ships you can get on the decks and jump down stairs to cargo hold which is empty and underwater on most of those. Problem: There are wooden beams blocking the stairs and you can't get back up. No other exits,stuck in water slow walk unable to jump.

4. Oxenfurt. Harbor flag.There is a house you can jump out of the window,over wooden walkway and into another. Well in that other house there is little jewelry box that you dont get a prompt to open.

5. I forgot exact spot but one of the bridges on the north or west of the starting landmass in Velen on the novi side has a special looking treasure chest on a guard tower. A wyvern is nearby I think. Problem is you can't reach it, no ladder,no jump,no aard,nothing.

6. Novigard. Lambert quest,after the water wheel and going to meet supervisor.Another unreachable chest on 2Fwooden in the courtyard. Should be easy climb via roofs but a wonky repelling is going on

7 Rescued a barber somewhere in Velen. Barber never showed up in a C named town' for free cuts.

8. Bandit camp, south most Velen. Had cannibals,got treasures, but the camp icon is still bright white after looting it
Its a touch north of a guarded treasure with a lv 28 bog hag of doom.

9. Secondary quest trigger problem. Most truest of Basilisks. Was exploring underwater and the icon appeared nearby. on far screen Not wanting to lose focus I ignored, didn't speak or view any event. It won't trigger again. Should require dismissive dialogue prompt not thinking I'm not going on that side of the river yet!

10. Finally Location Everywhere, Problem: Candles. Who stacks candles on top of loot? Who does is a million times? Mad men thats who. Candles r nice. Making Geralt shuffle step for a million prompts isnt

I want to bump this thread.
I'd like to add two other bugs:

11. Near the Cannibal camp at #8 above, just north near the slaughtered village there's a tent camp with a loot sack which is unlootable because unreachable.

12. Sometimes enemy bolts can pass through the trees. I got it by a Crossbowman at a fork with a bandit camp in Velen, while I was behind the big tree at the middle of the fork. I saw the bolt passing through the tree. This is bad especially because Geralt is entagled by very small branches.

Another bug, you can't kill the djinn if you enable level-scaling. The monster removes 3/4 of your health bar by hit...

This is still the case. Fought him for an hour before I gave up and looked online to see what I was doing wrong--turns out the game is bugged. When I turned off level scaling I beat him first try, without losing more than 20% of my HP.
