[FE8] Create enemy reinforcements that can't be blocked in FEBuilderGBA

Been a while since I’ve done any eventing… or much of any rom hacking, for that matter.
I’m trying to make a hack of the base game where something unkillable spawns in after 2 or 3 turns and starts chasing the player’s units, like the Green Demon from SM64, but it’s possible to stop them from spawning in by standing on where they’ll show up. Is there any way to prevent that from happening?

There is. You know how in unit placer you can give any unit more than one set of coordinates? Do that with the enemy unit you want to spawn. It can even be the same coordinates twice.

Oh hey, that works! Thanks a ton!!
And, uh…
…sorry in advance, heh.
