Sry, i have seen your question today .
The Prefab is build in Version 15 in Random Gen. With Coppi Mod or BC manager you can set it also in Navezgane i think,
but you have to convert it before with Hal9000 15to16 Converter because of some blockchanges.
I will try to make a Version 16 ready Prefab in the next time if i have enough time.
is this for navegen or random gen?
