The replicate spell / brush allows the user to copy and paste areas that are protected by world guard / grief prevention.

I think these made it into 8.7, and definitely will be in 9.0

No, there's just no care about where brushes source from, protection is about being able to build/break in a specific area.

There is no way to disable those brushes (for players that already have them), but I have made a note to add a way to disable them.

I understand! Though it is possible to disable specific spells inside protected regions using flags so I just thought there would be something similar for this.

Thanks for the info though, and thanks for adding the feature request :)

Copy from or copy to?

Copy from, though I haven't tested the other way around.

There are some builds around the map that are protected, and a user has been making copies of them. I am okay with them having engineering I would just prefer if protected areas couldn't be copied.

Can ask why?

There's nothing to prevent them copying from protected areas, but if they have the blocks or materia to afford it I don't see why its a problem.

Phantom said that the problem was because the user was outside the protected region when casting. So I thought perhaps it would have stopped them if they were inside the region. That led me to think it was just a bug causing this.

It's just a preference though I suppose.

Is there a way to disable the replicate brush?

The current dev build has these options, you can do these commands if you want to disable the brushes:

/mconfig configure config replicate_brush_enabled false
/mconfig configure config clone_brush_enabled false
