System Information
Operating system: Windows-10-10.0.17763-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 537.13

Blender Version
Broken: 3.6.4, 21bfc5e7fe3f, 2023-09-25 13:24
Worked: ???

Short description of error
To reproduce:
Clean file
Create an empty, create cube, parent cube,
Now try to append theese objects to another file.
All will work well. Until you add driver to emty`s transforms.
So add driver to empty transform (i made rotation from current_frame)
Try to append again. Blender will create whole new scene and place driven empty and cube there, instead main scene and active collection.

You can try with my file.

empty.blend

Here how it happens

Hi! I believe this is working as expected. Since the driver is referring the frame_current property from the "Scene" scene, then the empty has a dependency on "Scene" (otherwise it doesn't). So you can choose to use "Context property" mode for the driver variable, this way it will keep the reference to "Active Scene" instead of any specific scene, and this way you can append these objects without including the "Scene" scene.

Thanks for reporting, will close this issue :D

Thanks, i tested. Even if i use Active scene, blender do the same: creates new scene after append.

So is there a way to append to current scene?

For some reason it doesn't seem to append correctly now but it was working, let me check further.

OK here I'm able to append without creating a new scene:

First link the two objects, now you will have a linked scene "Scene".
Remove linked "Scene".
Append the same two objects again, now it will be appended into the current scene instead of creating a new scene.

This seems pretty weird.

Yup. So you see, it works very strange, not as common intuition say and not as it may be handy.

So I agree it can drag additional scene, when driver use exact scene, but in case of context/active scene it should be inserted right here, into active one.

You can see it is simple real case, where i want to append empty for fast turntable.
