In updater-view there is still the button for updating students individually: That can be removed and all the code related to it from backend and scheduler. It's only purpose was to try to debug the hops problem, but it didn't help and it's not useful (very slow too).
Also, is the monday/tuesday reupdate still necessary after HOPS was acually fixed? Still it seems that weekend update leaves some study plans not updated. Is this how it should be or not?
