title.

Commanding units creates a path that obeys their collision mask. Commanding unit groups uses a hardcoded collision mask. This means if you wanted to command a group of water-based or flying units, you would have to command each one individually.

I consider this solved with unit group collision masks depending on the members of the groups: https://factorio.com/blog/post/fff-345
