I was initially listed as the teacher of a course which will be available to students in our upcoming summer session. I will be leaving my current position so another teacher will be teaching the course. The teacher change was made within our institution so the course disappeared from my list of courses. However, the new teacher added me as a teacher so that we could work on the course together until I leave. After 24 hours, the course again disappeared from my list of courses and I was deleted from the "People" list in the course. I have been added, and subsequently had the course disappear, three times. Can anybody explain why this happens and, more importantly, what we can do to make it stop happening?
