Lix has a level that solves with 0 skills, but not obviously. Thus Forestidia's 3) is a concern: Cancelling the map produces a solution checkmark, that would look like a bug.

Color me curious, which level?  Is it part of the set of levels that come with Lix or just a custom one from somebody?

The other alternative is maybe the game just always keep the replay for the most recent attempt as a backup somewhere, regardless of whether it can possibly solve or has solved the level or not.

To copying pieces:

That copied pieces spawn a bit below the original can lead to the problem that they spawn outside of the reachable map if the original is too low on the screen edge. You can still reach them by increasing the lower map size though.

Alternatively, in DOS Lemmings you can hold down the right mouse button and then click with the left button to assign in "priority inversion mode".  Roughly speaking this will let you assign skill to the non-prioritized lemming instead, in situations where the cursor covers multiple lemmings and one is prioritized like the blocker.  In certain other ports like the Mac you would hold down some key like Alt to activate this mode instead of holding down right mouse button.  Not sure if this kind of option exists in Windows Lemmings.
