Instructors - there is a known issue in Moodle core that could impact your course. Â So far we have had only one report of this problem and have verified it does not impact every course system wide with the Simple Weighted Mean aggregation method.
Problem:
If you have a grade category with the aggregation method "Simple Weighted Mean of Grades" and add assignments to it - those items MAY have the extra credit box checked by default.
Solution:
Moodle core is aware of this problem and working on a solution. Â We have no estimated time for resolution.
To follow the development of this problem and its release into production visit this link:Â https://tracker.moodle.org/browse/MDL-48187Â
Please verify your gradebooks are accurate after adding a new graded activity. Â If you would like assistance verifying your gradebook or to test this problem in your course please contact the ATC (http://www.lanecc.edu/atc).
