@vincentknw I am unable to reproduce the behaviour you described. What I have done:

1. Create a couple of points, either on the same layer or on different layers.
2. Create a path between the points.
3. Select the points and the path.
4. Cut the selection via Ctrl+X.
5. Switch to a different layer.
6. Paste the selection via Ctrl+V.

The result is that all of the points and the path are present on the new layer. This also works with more than two points and/or when the points initially are on different layers.

If you can reproduce the issue, please describe in detail the steps to reproduce it.

1.create p1 and p2 in layer1;
2. new a layer2(layer2 activated), copy p1 and p2 into layer2, named p3 p4;
3. connect path p1-p2, p3-p4 in layer2
4. result: change visible of each layer , we can see p1 p2 in layer1 but path p1-p2 in layer2 , and i cant find anyway to change the layer of p1-p2
ps: people sometime forget to active the layer ,so mistake can happen obove,if i cut p1 ,path p1-p2 disappeared immidiately, after i paste it in another layer , i had to reconnect the path and add some properties
