Oh, shoot- I had it set to use the "Miner's Mug" when the item is called the "Miner Mug", that must've caused the issue. I'll do the whole "patch the patch" thing real quick, since I did just add this patch today.
Glad you like the new UI changes! In the future, I might shrink the text a bit to make room for some more stats, like Healing Rate and Action Meter Speed.
