Unless it changed with recent updates, you just need to go to Solitude, even fast travel worked. Find the horse at Kala's stable and proceed with the gate conversation.

Check if you have mods that chenga Solitude. The beggars could be stuck somewhere because of them. Trying reloading the save as well, if you don't have such mods.

If you have mods that change roads or add stuff to the river (like Northern Roads or Lux Via) it can bug the whole scene. You could use them if you delete the world references for the area.

Dogma said that there is no returning scene at the moment. He said the dialogue is mostly a placeholder because he didn't decide yet if it's necessary to add this scene.

if you have mods that changes Rorikstead, it can cause the scene to break like that

I asked Dogma and he said there is no proper scene with Gray Fox at Madam Petit. He is a regular costumer, appears there randomly among the other NPCs. It seems there a small interaction dialogue in which the heroine can realize that the guy she is dating is him, but from what he said, it's like she only realizes later and he goes away. I didn't bother trying to see it cause he said the scene is not different from other encounters except for this small bit.

The village will be the last thing he touches during this revision. So, yeah, there is a jump in the sense that there is no new content for the village. I think he made a patch for TNG, but don't know if it works. And yeah, Pandora works.

Probably won't mess up. I recommend Pandora, since it's the most modern.

Sorry to ask again, but is there any update planned for the near future or this year, maybe?

It shouldn't interfere. You should use FNIS or Pandora for the animations to work. If you are on Nemesis, it's not compatible

So far that's it. There will be more scenes once Dogma finishes revisiting the older parts of the mod. He will add missing stuff from Silentwood

Try using mods that can locate NPCs and teleport them to you, like Modex. You can search NPCs (Actors) by plugin, select the Thief one and type Jona, then make her teleport to you (don't use the place option or it will make a copy of her, and watch out for not teleporting you to her). From what I remember you need to leave Falkreath and then the house should appear. Took me some fast travels here and there to trigger it. I think the courier should also bring you a letter from him

If you have mods that changes the New Gnisis, disable it. She should be sitting in a table in front of the bar.

Go to their hideout in front of Bryling's house and talk with them

iirc should be behind the waterfall
