I have a unit that appears on the overhead for the enemy, but after picking up an artifact I want it to be invisible on the overhead for the enemy. Is this possible? I've been trying but nothing so far works.

Afaik you'll need to create a separate mons (monster) in Fear that said unit becomes when they pick up the artifact.

In that mons tag under "Flags..." check "Invisible on Overhead Map".

That should do the trick.
