For some reason when you browse through equipped inventory slots, it seems that some of the slots for chest/gloves will be skipped when trying to arrow onto them to highlight.
It’s as if the back end registers the slot placement differently from how they are visually displayed and will skip over certain slots, then jump back to them after you’ve past over them visually.
I had a few times where I was confused and chasing to try and hover over my equipped chest piece to see its stats, but the highlight kept skipping over it to the slots before and after.
