I found out the problem. I was expecting the multiply to work like with GLM where you could do: 

translation * rotation

but with the operator overloads I need to do protation * translation. Anthony’s multiply matrix 4 operators did this in the order I expected and how I figured it out. Not sure why and it’s probably not safe to swap the parameters because it would likely break other parts of the unit.
