vectors "jumping" unexpectedly
Hello, whenever the output of a user tool comprises vectors, and when I use several instances of the same tool on different objects, the vectors from the previous instance "jump" at the location of the new instance. If I move the input objects of the first instance, the vectors "jump" back in their initial position, but then the vectors of the second instance jump also!!!
This has been happening since years. I took the habit of not having vectors as output of user tools, but sometimes it is useful! (lists of vectors work, they do not "jump". But lists are not always convenient as you can't select an item by clicking on it).
Has anyone an idea how to work around this?
Is there a plan to solve this problem?
Note: Points work. So a turn around is to have points as output which I then must link to create vectors. But it doesn't show what is the direction of the vector, so it takes time to find this direction by other methods...
