Bug ?

[saemar]

I wanted to know the invisible fence if it keeps all animals away or there are exceptions.
I happened to make a piece of invisible fence, but the wild dogs passed it without problem.
I also encountered a similar problem with mandrills. They climbed a nearby tree and jumped the fence.
Is there a need for attention or is it a bug?

If you use the invisible fence you need to have other things like rocks, terrain modification, foliage or building pieces that stops the animals from escaping, beacause the invisible fence is not a fence, it doesn't stop the animals.

As Arrakai says, the null barrier is a tool to allow you to use natural features or building pieces to create custom barriers. The null barrier on its own does not prevent animals from escaping.

It's worth using the null barrier and putting in the work to actually close it all up with the rocks or construction pieces. Null barrier is the only one in the game which does not require maintenance and it never degrades (unless that's been changed since).
