When the summer semester is more or less over (officially it ends with the 30th Sep), specific courses can't be found by SAM. Because of this students can't assign course roles to themselve.
This happens because of the filter +cy (current year) which is being used for filtering the course results. With beginning of July, u:find seems to preemptively move on to the next study year which results in courses being filtered if they don't have a course page for the upcoming semester already.
