Hi Martin, you can try with virtual inheritance (not in the sense of dynamic polymorphism). I just found this: https://isocpp.org/wiki/faq/multiple-inheritance#virtual-inheritance-where <https://isocpp.org/wiki/faq/multiple-inheritance#virtual-inheritance-where>
This may help, I hope it does! Best, Dennis > On 22.
