This one’s a bit complicated, but I think I can reproduce it reliably.
Setup:
A
-B
-B
-B
-B
C
-D
-E
Where window is short enough (or there are enough actions above A…) that D ends up at or near the bottom of the window…
Now, copy/drag (ctrl+drag) A onto C, producing this:
A
-B
-B
-B
-G
C
-D
-E
-A’
–B’
–B’
–B’
–G’
That works ok, but the scrolling for the window gets broken - the scrollable area of the window doesn’t get expanded to take into account the extra nodes, meaning you can’t reach G’. If you try and use the keyboard to navigate down, all sorts of nasty visual glitches appear.
If you shut down and restart FB, it’s fixed.

Thanks Steve. We’ll look into it (I could reproduce it 2/3 times, so it seems pretty reproducible.)
In the meantime, it may be safef to use Ctrl-C + Ctrl-V to copy sections of action list, instead of drag & drop.
