# RESOLVED: Missing Modules Issue Tuesday, September 4th Due to an unexpected issue some students may have incorrectly received a “missing modules” error from on Tuesday, September 4th, 2018 from 4:30PM – 5:10PM Eastern time. This issue would have prevented students from completing SIMnet 2016 assignments during this timeframe. Students may need to logout of SIMnet prior to attempting another assignment.
