When my map is loaded, these warnings pop :

> LogPhysics: Warning: PopulatePhysXGeometryAndTransform(Convex): ConvexElem has invalid transform  
> LogPhysics: Warning: ForeachShape(Convex): ScaledElem[0] invalid  
> LogPhysics: Warning: PopulatePhysXGeometryAndTransform(Convex): ConvexElem has invalid transform  
> LogPhysics: Warning: ForeachShape(Convex): ScaledElem[0] invalid  
> LogPhysics: Warning: PopulatePhysXGeometryAndTransform(Convex): ConvexElem has invalid transform  
> LogPhysics: Warning: ForeachShape(Convex): ScaledElem[0] invalid  
> LogPhysics: Warning: PopulatePhysXGeometryAndTransform(Convex): ConvexElem has invalid transform  
> LogPhysics: Warning: ForeachShape(Convex): ScaledElem[0] invalid

Nothing about the origin of the problem. Is it a problem with some static mesh collision ? How can I find which one is wrong ?

I found the culprit by checking the blueprints… for hours…  
A variable (value 1000000) divided by 0.1. Removing it or replacing with a \* 10 fixes this.
