I went through and did some tests. The left and right did not matter in the Construction Set on NPC's, whether it was two lefts, two rights, or one of each, only one item would be visible, and it was always the last item that was put into their inventory. I am also 100% sure that I did not have any items hiding my rings (I ran tests with only rings and ring slot items equipped). I performed tests in game on my player character, and no ring slot items (left or right alone, or any combination of them) would appear on the character. My tail slot, lower leg slot, and amulet slot items all work perfectly, as do my regular in game items. My ring slot items that use the ring model also function properly (including one that fills the shield slot). Does the ring slot only work for items using ring models? Any information would be helpful. Thanks again. -BenG4499
