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:

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?
