You have a strange building panel... did you take this screenshot from the internet? There's an extra building stage on the panel that doesn't belong there.

This is a screenshot from the game. I'm editing the Universe mod.

A strange error popped up, even though I haven't changed the visuals since I modified the archers. And they passed the tests successfully.
"DB Error
Creature #3 has no visual or its missed."

UPD: I managed to locate the problem, but I don't understand its cause. It's the archers and crossbowmen. Everything used to work, even though I haven't changed the archers' visuals, only removed the arc shot.
