This is mainly a game bug, but since it affects mainly the asura characters, I think it has a good spot here, too. Allow me to copy my earlier post I made on the bugfixing forums:
“Race: Asura
Sex: Female
Class: Guardian and Warrior; basically, heavy armor users.
Armor piece causing the issue: Pit Fighter coat/Leika’s breastplate/Seraph-Issue Breastplate
Two of my characters are wearing these two chest armors, each of them has its looks transmuted to another armor. I’d like to note that this has no relevance, the armor causes glitching normally, and transmuted, too.
When it is worn, and the character has her weapons unsheathed, the weapons are misplaced and are clipping through her wrists. I tried unequipping other pieces of armor, but only by removing the chestplate was it gone, and it returned when I re-equipped.
This error is persistent and was in the game for about five months now. Please do something about it, because I wouldn’t want to change my character’s wardrobe, and it is sticking out like a sore thumb."
I came to realize that a lot of other players had similar problems with other armors as well. I would like to see this fixed as soon as possible, since I don’t think asuras want weapons in their main arteries.
