Not sure if this is a dupe of #455 but the console gets spammed by the following lines on startup:

I tried emptying the sql database, but after another reboot, the same thing happens. I think it keeps trying to generate pre existing entries.

Yep it's a duplicate.

Perfectly safe to ignore, I just re-enabled the stacktrace output on the dev builds to help track down a case where some installations weren't adding the soft column correctly.

What about this? This pops up after the server's been running for a few hours:

This probably belongs here: #446
