I worked extensively with Moodle back in college as part of IT. Moodle is pretty solid, but had numerous bugs. We were one of the few colleges that used the most up-to-date version of Moodle when it came out. One year, Moodle replaced its default grading setting with something called (if I recall correctly) Natural grading. We tested it and had professors try it out. Natural grading seemed fine at first, but then professors started noticing issues after a couple of days. The math just didn't seem right. We went through multiple courses, looked at grades, and calculated averages - everything was slightly off! We switched all classes that tried the new grading back to the old default. No one could really figure out what was going on. It wasn't exactly clear what math they were using. As it turns out, we were one of the very few that updated to the latest version. We even got a phone call from a university that saw we were using the newest version and asked what we did to solve the natural grading issue. Another time, a year or so later, I went to submit some homework through Moodle. I realized that my professor used the wrong setting for his assignments, making it so that I couldn't re-submit an assignment. I could have logged into my administrator account and helped him, but that also would get me very, very fired (and possibly jeopardize me being a student). Instead, I inspected the UI and realized that Moodle was actually rendering all buttons, and then using CSS to hide them based upon the settings the professor chose. I un-hid the submission button, and then re-submitted my homework. At the end of the day, Moodle was pretty good. Despite these experiences, I still view it very fondly.
