Invisible Monk
 

I ran Raev and Loraen to the Halls of Testing for kicks. Loraen was visible on Raev's screen; Raev was not visible on Loraen's screen. Raev was able to invite Loraen to a group and appeared with normal full health. I was able to cast spells on Raev as Loraen. He just didn't appear on the screen at all.

ed: eventually he did show up. Lasted about 5 minutes.

did you zone the two characters in at the same time?

Loraen zoned in about 5 minutes after Raev iirc

ah was gonna say there is a bug on red where if two people zone in at the same time one of them will be invis to the other. this doesnt always happen but ive died and i've also killed people this way. you wont see the other person in zone on /who or visually.

Both showed up on each others /who
