AI Pawns Move outside of Nav Mesh to reach Destination

My nav mesh bounds appears to avoid certain Destructible meshes in the level, yet my pawns seem to walk straight through the destructible meshes.

Is there a way to make the pawns stick to strictly following the NavMesh bounds? As these Pawns collide with the Destructible mesh and fracture them, rather than walking around them instead.

I have attached a sketch to explain what I mean.

Any help with this would be appreciated, thanks.

Can you show a screnshot of the nav mesh/Navigation area on the map? and does the destructable mesh block navigation?

I realised that I had missed out the “Can Effect Nav Mesh” tick box…

I’ve only been using the engine for nearly 3 years to make such a noob mistake lol.

Pitiful noob mistake after using the engine for many years. I did not tick the “can effect Nav mesh” boxes lol.
