When you cloack if you look at her weapons you will it notice that they won't cloack instantly. Her hair randomly grows too :roll: http://www.youtube.com/watch?v=A8Z-1z7cCcg&t=0m30s
Not really a bug. The weapon cloaks when the the player is considered "fully cloaked". Until your weapon cloaks fodder and turrets can still see you. If anything the bug is you visually cloak faster than you should. The hair issue is something I was actually looking at today, not sure if I'll fix it. Really, it's nice people are playing the game enough to be nit picking some minor polish issues.
Perhaps her hair becomes covered in a coating of inviso-nanites that are for some reason really thick and more noticable than the term "nanite" implies.
