The unopened trapped chest and centennial trophy show the magenta and black missing texture thing. I did check the assets in the jar, and the unopened trapped chest texture is in there and spelled correctly, so whatever the deal is, it's beyond me. Oh and I have no resource packs installed.

Also worth noting that the opened trapped chest is completely fine and renders correctly as soon as I open it.

Whoops!

Okay, I've made a release that should fix this.
