My little brother is having trouble woth the caveman quest.

[Famix]

I guess we need to save a cavewoman, but he says he removed her. How do I fix this?

[hymn]

A screenshot would be helpful to know which quest it might be.

But if you can remove a character with the discovery tool that means you have already discovered it so maybe simply placing a new one next to the quest giver solves it.

We're on Xbox :/

I tried placeing cavewomen, but nothing happened

In general an NPC should respawn if it's part of a quest, perhaps it did but in the wrong spot.

I figure it's one of the tutorial worlds with required quests to collect enough gold bricks to go to the next world?

You can reset those worlds if you can't find another solution, travel back to the Pirate world, go to the Galaxy Map select the Prehistoric Peril world and delete it, a new one will be generated.

Starting over would be the other option, first world is like 4minutes.

How do I delete it?

Because that sounds like a good option.

[hymn]

You delete a world by going to the Galaxy Map, selecting the world you wish to delete, has to be one you're not currently on, then press X to show the world option buttons, 3rd button from the right has a trash can icon which deletes the selected world.
