[Bug] Occasionally, Window Fails to Fill, Spamming Stack Trace Instead

When it happens, the main view renders only a couple pawns (presumably until it hits the error row) and then suddenly renders no more pawns.

It happens on the GUI thread, so it spams the below stack trace error a bajillion times per second until the window is closed.

I narrowed this one down, it happens when Current Job column is selected and a pawn is Downed.

Actually, can't quite replicate this one consistently, might be related to #21, which I was able to replicate, but the stack trace was different here ...

Closing #17 as a duplicate in favor of #21
