On December 4 I upgraded from 3.9+ to 3.10+ on moodle.msgcnx.com. right after that files started randomly dissappearing. For a given assignment 10 students may have submitted. 5 of them have missing files. The submission page looks normal. BUT when you click on the file you get an error. The error message is below. I have searched for hours in the Moodle database in the Mdl-Files. The submission is properly received and hashed. HOWEVER when you follow the content hash to the path in moodledata/filedir there is nothing there. The other student's whose files work look the same in the database and their files are in the filedir.
It just seems that either Moodle never puts the file where it belongs or the database blinks.
Thanks in advance for any and all help.
