Navigation relevant Actor coudnt link to Navmesh

Hello, everyone,

I’m creating a level block-out in the Unreal Tournament Editor and after I put the Pickups and Weapon bases I get a mapcheck flooded with warnings (928 to be exact) everytime I update a BSP or other object. It says: “Navigation relevant to Actor coudnt link to Navmesh” for each of my objects. I updated their position and the position of my NavMeshBoundsVolume, but no result. Every once in a while Unreal crashes because of this. Any ideas?

I searched for someone with the same /similar problem, but I failed. Please, redirect me if I missed anything. Thanks!
