concave MeshColliders are not supported

[LanieSoftware]

I'm getting this message in the console:

Triggers on concave MeshColliders are not supported
UnityEngine.Collider:set_isTrigger(Boolean)
CelestialBodyGenerator:HandleGameModeGeneration() (at Assets/Solar-System-Episode_02/Assets/Celestial Body/Scripts/CelestialBodyGenerator.cs:90)
CelestialBodyGenerator:Start() (at Assets/Solar-System-Episode_02/Assets/Celestial Body/Scripts/CelestialBodyGenerator.cs:42)

It does work, nonetheless, for what I'm using it for, but I assume something could/should be done about this issue. I'm just not that well versed in Unity (yet?) to figure it out.

Old, but I can't leave this without any clarification ;p
I don't think this is that big of an issue, I recall it getting raised but there were no obvious problems. Plus, it's referring to triggers - I don't remember any trigger in this project either.
