Ever since I updated to 1.2.0, I noticed dynamo started to remember what it did in a previous section. For example, I have a script that places adaptive components. After using it to place adaptive component A, B, and C, I save and close off dynamo, The next time I open and run the same script to place component D, E and F, it still remembers A, B, and C and would delete them. Currently my work around is to not save the script after placing the Revit elements, or to cut and paste in same location so that they would have a different element ID.
I hope there is a better way out there to fix this because many times I would for get to do either of the above and having to repeat the work. I guess it makes sense in some situations but I would really love the option of turning this feature off.
