Name of professors not offering the course appearing as teaching it

[Rico-CHEH]

Problem Description

For some courses such as comp 330 or math 547, the professors appearing as currently teaching does not coincide with the actual information on the website. Example below:

This shows that both Matthieu and Claude are supposed to teach the course for this winter semester, because originally Claude was supposed to teach it but it was changed in the middle of fall semester to Matthieu, since Claude left McGill. (Similar situation for math 547, because Linan Chen was supposed to teach it, but it got changed in the middle of last semester).

Idea

I didn't look too much at the code to try and find what caused it, but my guess is that whenever it detects a change in the page, it updates the database with the new prof, however it never checks whether the previous one remains.

Hope this helps

Fixed in #631. Thanks for reporting! We're working on automating this type of manual data retrieval so stuff like this happens less often.

Reopening because the issue is still up on prod (? confusing

Not sure if it's a related issue but MATH 141's S2024 says the course was taught by Hovsep Mazakian but it was in fact taught by Elio Abi Younes. McGill's own website reflects this inaccurately, showing that both lecturers taught during S2024, but then why doesn't it show both names? Edit: see comment below

Sorry I just realized there were two separate sessions for this course over the summer (potential root cause?), so the data from McGill's site is correct. But anyhow both lecturer names should be displayed
