Why won't units load into the map, even when I add them through the unit placer? (FE8)

Note: I’m using Fe Builder.

I’m not the best at explaining things, but basically what’s happening is that when I test the map in the emulator, the characters I add refuse to load in. This started happening a few days ago on my project where I attempted to add two characters to chapter 21 (We’ll call them Morgan and Validar.) Both Morgan and Validar were added through making a new set of units, adding an event to make them appear at turn 4, and then boom. They were supposed to appear, but for some reason, when I booted up the file and got to turn 4, they never appeared. I tried removing things in the event (A conversation and an event battle), but nothing worked. Eventually I just gave up and removed them from the chapter. A similar thing happened today in the chapter with all the monsters and lava, when I put a different NPC unit in the chapter start event category.

This hasn’t happened before, as I have replaced reinforcements, added new ones, etc. before.

Hopefully this gets reach.

Can you send some detailed screenshots about what your problem is? (like both from the event, unit placements, what event are you trying to do, etc)

Tell me, how many units did you load on the map? In GBA there’s a limit for them in playable units I can’t remember, but for enemy units are 50

The amount of units was definitely not 50. It was 39 + reinforcements on Final part 1. And 29 + the reinforcements on chapter 18.

Why didn’t you show the event which loads him onto the map? That would be nice information to have to solve this problem about why he’s not being loaded onto the map.
