[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 can replicate this one, it happens when a pawn is downed, there is a short delay between when they are first downed and when the word "Downed" appears on their infobox in the lower left corner, as evidenced in these two screenshots, taken moments apart:

During the gap in between, if Numbers is opened, this stack trace is thrown repeatedly, regardless of columns selected, even if no columns are selected at all.

Might be related to #17 , not sure.

Definitely related, the above replication steps still hold, I have seen both stack traces, here is the other stack trace for reference, but I have (somehow) seem both during the same replication steps, so the issue is the same.

Closing #17 as a duplicate in favor of #21

Was on 0.6.1, didn't see new release 0.6.2, still replicating in 0.6.2, although now it is only thrown when "Current Job" is a selected column, or there is something inconsistent happening here.

Regardless, issue is consistently replicable by selecting "Current Job" column, pausing the game, using DevTool "Tool: Down" on a pawn, then opening Numbers.

Not sure if there is another subtly different bug lurking in this same comment chain, but I couldn't find enough of a difference to warrant two open tickets.
