Action A
Action B
1. Select both actions (ctrl+click)
2. Drag-copy both actions (ctrl+drag)
You seem to end up with:
Action B’

Could be similiar to the copy bug I found:

yep, looks like it’s the same 
Steve,
This has been fixed for the next test build. It actually happens whenever you either copy or move multiple sibling actions, as long as you “insert after” when you drop them (if you drag them to become children, or drag them to insert above a given action, the problem does not occur.)
Thanks for reporting it.
