Unknown unit when trying to do a follow macro

[MiRai]

Whenever I do the FTL follow keymap I get an "unknown unit" error on all of my slaves. What could cause this?

Usually caused by not having the addon enabled on your team, or having some sort of FTL conflicting modifier. If this error occurs while you're playing any of the team members then it's likely the addon or you've put a modifier key into your hotkey/key combination in ISBoxer. If it's only select characters that this error occurs from then it's an FTL modifier conflict or again, the addon is disabled on that particular character.

Last but not least...

Characters could be logged into the incorrect slots [I believe].
