Before when in party, the bars would just go grey when a person left the room or got out of site. Now they completely dissappear when they get out of range or go to another room. They screwed up the party bars now
Though the travesty bar now stays up when u pull it. So they fixed one thing and screwed up another.
Has anyone noticed this problem??

Yep. Its 50/50 now.
In party, person hid, bar went bye-bye. 20 minutes later, did it again, but bar stayed and went grey like it used to or is supposed to.

Can't say it fixed anything, however, it may need Shard publish to be fully functional, yet to be seen.

Right now its proceed with extreme caution.

Aaaaaaah!! Our party threw caution to the wind last night, and paid dearly in insurance gp. There does seem to be a work around... use 3D client and no problems with disappearing party or health bars, but that makes me nauseous and gives me a headache too. Guess I'm going to need to earn more insurance money or hope for a timely fix from our Dev Team.

So youre saying that when Travesty Invises, the bar stays up huh? That could really suck in a pvp field fight. Say youre fighting someone with hiding. You pull their bar up, they kinda run off and hide or something like that. You go around just revealing their health bar until they pop up. Seems like kind of a screwjob on people with hiding. Youre not supposed to know where they hide, they have to find you. Now they can just click on the bar.

nope, doesn't work like that. Can't target on a greyed out bar.
My husband and I tested it. His stealther hid on one pc. I used his legendary mage on the other and could not reveal him.

Good deal. I was thinking that was going to be a really crappy side effect of this new patch.
