2.0 and 2.0.1, all local instances
If you export and re-import a timed assessment, the timer and auto-submit settings may be reset to the defaults in the imported version.
Also, when you preview the imported assessment, the timer will be reset to 0 (no matter what it says in the settings), and so the assessment can't be previewed.
Settings information lost in mysql instance, but not in hsql or oracle.
Preview messed up in all 3 versions.
