Проблема с "Unable to cast skill ... in 3 tries"

[ShtacketT]

Периодически в консоль выводятся сообщения вида "Unable to cast skill ... in 3 tries". Проблема возникает только тогда, когда скилл юзается из макроса. Например:

Код макроса:

macro doCallSpirit {
	log Calling spirits
	$i = $.spirits
	while ($i < 5) as callspirit
		do ss 261
		pause 2
		$i++
	end callspirit
}

Консоль:

Или макрос

macro doWarp {
	log Warping
	$x = @eval($::char->{pos}{x})
	$y = @eval($::char->{pos}{y})
	$x1 = $x + @random("-1", "1")
	$y1 = $y + @random("-1", "0")
	do sl 27 @eval($x1) @eval($y1)
	pause 3 
	do warp 1
	pause 3
	do move @eval($x1) @eval($y1)
}

Как видно, сначала кора пишет, что мы 3 раза обломались с юзанием скилла, а потом косвенно сообщает, что скилл юзанулся отлично. В чем может быть проблема?
