Any way to "regenerate" a chunk?

[Broccoli Clock]

I activated a translocator, but never explored the area, this left a little circle in my map (with the "fog of war" surrounding it), however when I finally go to that location on foot, the map doesn't match up.

This is the map..

You can see the original area discovered, in the black circle, and you can see that the map does not line up.

This is what it looks like in game..

I am using the Terra Prety mod, and I have a feeling that's what has caused this, and I could live with it, but I'd rather not. 

What to do? Can I get either the vanilla game, or Terra Prety to redraw this chunk "properly"?

 

Thanks in advance.

Maybe the command they were talking about in the 1.21.5 post?

Thanks for the reply.

What command are you talking about? Is it the /prune command that is part of the 1.21.5 devlog? https://www.vintagestory.at/blog.html/

If so, it does say..

Fixed: Command /db prune should now work properly.  [Notes: Use with care, it's a powerful command, can take a few seconds or minutes to run. Essentially it can remove parts of the map already generated in earlier game versions so that they can be regenerated with fresh 1.21.5 worldgen and bugfixes, while preserving any parts of the map which have player builds, farms, roads or mines. A backup of the world first is advisable] 

 

It does sound like it could be a solution, I will look into it. Sadly prune isn't part of the Wiki yet. I see there is a /wgen command but it only talks about tidying up chunk borders rather than regenerating the complete chunk (which I believe is probably what I'll need to do.

Is it on the creative command handbook?

I think I have a solution, at least in a small test it's working, using the /wgen regen 1 command it rebuilds the terrain. 

I have swapped to creative to do this, but here is a video of it working.. https://streamable.com/q30xnx

Now, will it work "completely" I have no idea, I await what the final outcome will be!

Ok, definitely that seems to have fixed whatever issue I was having, as people may have guessed the "1" prefix at the end of the regen command is the number of blocks that are regenerated. As it was quite a large area (and the chunks are smaller than I thought) I raised that number up. Heh, just be warned that it'll take a while the higher you go! I tried 64, my machine completed the regen but not without a considerable delay.

Another interesting thing is if you regen'ed larger than your view distance, the land will regen but the map remains, you have to physically go to the location (or up your view distance) in order for it to re-render on the map.

@Facethief You're initial comment was correct, although I used the regen rather than the prune command, both are listed in the 1.25.1 maintenance patch. So thanks for pointing me in that direction.
