It happens at the very start of the battle. I get to see that the map is loaded, with placement icons, behind the blurry rpgm mz error screen.
I cannot start the battle or place my actor.
This is what comes up, as soon as I start the battle. I can see blurry green arrow placements in the middle of the map, so it seems the map has loaded. And you can see the buttons Start and continue buttons in the top right. No enemies. On this map, there should only be a single spawned enemy and a single actor.
