Connecting multiple object pins as inputs to the Target input pin of an interface message node causes an error of the format:
This should either report a proper error that's actionable OR this should compile and follow the same patterns as function call nodes typically do for multiple Target pin inputs OR connecting multiple input pins to an interface message node's Target pin should not be allowed and should properly replace the existing input action.
Create an interface with a single function. No additional changes needed to the interface or function.
In another blueprint, create a message call node to the interface function. Connect multiple object pins as inputs to the Target pin of the interface message node.
When compiling, an error will appear:
