Main quest bugged

[Cold Jin]

BEWARE, SPOILERS AHEAD!

Hey guys, I need help. I'm stuck on the main quest because of a bug that won't let me go forth. The quest I talk about is the one in Kaer Morhen, when you gotta meet Lambert to retrieve some kind of thing for Yen's megascope. You have to get on the boat with him and he says that he will drive it. As as I get into the boat, nothing happens. I already had the same issue with Yen's mission "The last wish", which I ended up completing thanks to a bug - that is to say that the same situation happened but, after completing another quest, I returned to the boat where Yen was waiting and she was gone, thus letting me drive the boat and automatically start the question. I was hoping for something similar to happen with this one but...
Lambert isn't inside the boat anymore, instead a new quest marker labeled "Meet Lambert whenever you're ready" appeared. As I try to talk to him, the only answer I get is a passive (as in not-in-dialogue) "Geralt?" followed by nothing else. If I try to switch marker and return to "get into the boat", I can take control of it but nothing happens. The quest doesn't start.
This bothers me A LOT since it's required to go ahead with the main quest. Anybody had the same issue or knows a way to work it around?
Thank you and sorry for my English!

you have to sit down on the boat. on the other side from the person driving.

[Mark]

Did you sit on the other side of the boat?

Try to go to the Cave on the north east of the drifted boat. There's a narrow mountain, and that is the cave entrance.

Try to manually reach the opposite side of the lake and get into the caves. Continue your journey, it will have some dialogues and cutscenes on the way that will hopefully fix it.

BTW yeah, try to sit on the nose of the boat.

Thanks for all the feedback.
I was told about the nose of the boat thing when I was stuck with Yen's quest, and yet when I approach the spot there's no sign that tell me I can sit there, not even if I keep pressing E towards the nose. That's pretty weird, it happened in the previous quest and it's happening right now.
I'll try and reach the cave, I hope it works so that I don't have to go all the way back to another save file. Thanks again for the help!

[Cold Jin]

Uhm, I might need help again. I went through the quest correctly by entering the cave: that triggered a cutscene which started the quest. The thing is that running's been toggled off. I thought at first that if was because of the mission, not to wake up the "Old Speartip" (or whatever its name is in English), but I couldn't move any faster than walking very slowly neither in any following quest. How come this happened? Do you know if there's a way to toggle running back on? Sorry, I know I'm a mess, but any help would be appreciated.

I assume you already tried CTRL or SHIFT as well as saving-reloading, otherwise its a new bug I havent heard of before.

naw..I think the quests mecanic is like that since you are about to sneak up on him and suprise him(old speartip)..and you can´t do that by running. =P

No, you can run there. You only wake him up if you start cutting or aarding the rocks instead of climbing them. And he said he cant run even after that quest.

[Chrille]

..right. missed that part. couse it was like this for me too but it was ok after I´ve killed the old speartip.

Had to load an old saving and went all through the quests I did in the meanwhile. A pain in the arse, but since neither re-launching the game worked... Thank you all so much. Thread closed, methinks.
