General Question about Node Memory

I am trying to understand a phenomenon, I experience in Dynamo.

At times it appears like some nodes maintain information even after their input information has changed.

Input data A is processed in a script and Exports out data B

Run the same scrip expecting data B to be used for the input, but Dynamo remembers it had data A previously and unless I close the procedure and reopen it does not consider that the data was changed.

Can someone help me understand this… and which nodes I should expect this behavior from.

Thank you,

Just realized this issue has been resolved in 0.8.1
