Packaging Error

When ever I start packaging my game I always get this error message “LogUnrealMath: Error: FMatrix::InverseFast(), trying to invert a non-invertible matrix, this results in NaNs! Use Inverse() instead.” How do I fix it?

The only thing that comes to mind is this: (For me it’s Mac, I don’t know anything about other platforms)

Hope this helps but I’m on windows 64-bit
