@ulrik Compiling networks with cloned nodes is a tricky business.
How complex is your network? Maybe try stripping it back and seeing if you can identify a specific thing that's causing the error. In my experience, the min/max node will not compile in a clone.
So this compiles:

Whereas this gives the same 'reference to non-static member function must be called' error message as you posted.
