The other day me & my roomie updated to Thaumcraft version 4.1.1.14, and (lackaday) he died from a creeper attack; but the only items he dropped were his baubles (and then, only ones that were equipped his baubles inventory)

We tested this a few times, and each time he died the only items dropped were the baubles he had equipped.

I'm gonna shamelessly point out my PR #23 here.

This should be fixed in the latest version of Baubles.

1.0.0.13 is not by a long strech the latest version.

1.0.0.13 is what the latest version of Thaumcraft installed, 4 days ago.

So apparently this was fixed 3 weeks and 3 revisions ago.
Should file the bug with thaumcraft then.

Not fixed in 1.0.0.13. If I have anything in my baubles inventory, my normal inventory won't drop. Only equipped rings/belts and XP orbs.

Tried with full inventory + mundane ring and belt, died to a witch -> ring and belt dropped (+xp)
Tried with mundane belt equipped and mundane ring in my hand -> belt dropped (+xp)

Fresh forge-recommended and Thaumcraft install 4 days ago.
