First let me point out I tried to make this bug report in game on Xbox and it crashed everytime I hit start after typing the message.

After putting Yolna on my necro tank, it seemed like bone armor wasn't doing much anymore so I investigated and I might have an issue. I am wearing Yolna body armor, Warrior-poet jewelry, weapons, and shields, and Mighty Chudan monster helm. My character sheet no longer reflects the spell and physical resistance buffs from Bone Armor. If I take Yolna off and/or put on another body set and activate Bone Armor, I see the buffs reflected on my character sheet, in that the resistance scores raise by the correct amount. If I put on even one piece of Yolna, the scores no longer rise from the Bone Armor buff.
