After upgrading to version 1.8 (just updated to latest as of last evening, 3.april, in case a fix was already there),
uploaded assignments (using upload single file option) are not showing where they need to -

with some uploads present, the

"view 0 submitted assignments" link still reads 0;

on the Assignment > Submissions page, the uploaded files do not show up in the "Last Modified (student)" space

However, if the "Grade" link is clicked to open up the grading window, the link to the uploaded file does appear in that window, and the file can be opened from here.

(all had been working fine with version 1.7+, prior to upgrading to 1.8)
