Trying to add a student to a group with submissions already caused this warning:
"Careful! Changes to group membership will apply to groups that already have assignment submissions. Group assignment submissions may not align as a result."
What does it mean when group assignment submissions may not align? Will group submissions no longer work? Will the grading no longer pass on the grades properly? Is this the easier option to choose, rather than having to duplicate the whole group set?
Essentially, I just want that student in that group now, and if there are group assignments, all students in that group can see their marks.
