Blight Bosses in your Maps have X% chance to add an additional Reward Chest when Defeated

Does this really work? It never does for me.

I haven't seen it in the "Known Issues" page and other old forum posts seem to indicate it has probably never worked.

Why is that issue not looked at? Why isn't it -at least- in the known issues list?

It does not look like a big problem to fix, it might not be "urgent" but it has been a year though so what goes?
