How to stop the XP going to the farthest date line
My school, called Superschool, is having some problems with this. I put my one student on 20 XP per day, with the date due being one day after the other. He did 20 XP, but it went to the one that was due in six days instead of the one due in six hours. Therefore, i had to delete all of the 20 XP assignments. So my school is failing. Horribly. Please, someone tell me how to stop this. Please.
