Issue was discovered in 2.2.16.0 but also happens in 2.2.16.1 (just quickly checked it).

Trying to sort by Input (or by anything in items and fluids tab) causing the following error:

System.InvalidOperationException: Failed to compare two elements in the array. ---> System.InvalidCastException: Unable to cast object of type 'Foreman.ItemQualityPair' to type 'Foreman.DataObjectBase'.
