Terrain FillRegion() on client not working

I am creating a game with procedurally generated terrain that goes on as long as a player walks, for this reason, the terrain is client sided. Currently I have made it so players can dig using FillRegion(). It seems that once players walk too far from spawn, they can no longer dig. It’s very weird because everything still prints, it’s as if there is a barrier. Players also can not dig down past a certain point. I really need help with this, I’ve hit a roadblock.

Example

Hmm. Seems weird, either an issue in your code or a :bug:

Damn, I don’t think it would be my code because it just raycast from the mouse towards the ground and fills a 3*3 region with air where the ray.Position is.
