Yeah I figured this was not "intentional".

It would be way better if enemy AI knows how to move a character always.
But even in cases where it might be truly impossible... just - just have that character be passed by without a notice.
It is okay.
We do not need to see that this guy cannot do anything.

That is what I mean.
Only actual movement ( or invisible movement wink ) must be highlighted.
Everything else just does not make sense.

Just jump over them to the next.
