Bug report: Performance Average (Robust)

Hello,

I have a collection of performance vectors that I need to apply this average operator to and I'm getting this error.


Here's the report:

Exception: java.lang.RuntimeException
Message: Clone of average vector is not supported: Cannot clone averagable: com.rapidminer.extension.operator.performance.AreaUnderPRC$Neutral.(com.rapidminer.extension.operator.performance.AreaUnderPRC$Neutral)
