The step-by-step animation lives in the lesson text at res://course/lesson-18-for-loops/lesson.bbcode, and the practice code in the report is the move_to_bottom loop that increments cell.y. Read how the lesson decomposes the loop over time and compare it with how the practice runs the loop instantly. Done means a learner cannot mistake the loop for a delayed, step-by-step process, though the maintainers may need to decide whether the fix is in the lesson animation or the explanation.

There's an issue in the lessons that decompose the motion over time to show what the loop is doing step by step, but it's not done well. It leads to thinking that a loop does not apply instantly. This user was then understandably expected their loop in the practice to move the robot step by step with visual pauses.

somehow the robot animation just jump right to the end, my solution are checked fine though

Code from the current practice

var board_size = Vector2(5, 5)
var cell = Vector2(2, 0)

func move_to_bottom():
	for i in (board_size.y - 1):
		cell.y = cell.y + 1
