Cloaking/Hide disable HP bar

[Yoshu 5]

Hi everyone I'm not sure to be in the good section but I'll post here.

 

There is a little problem with my client (server ?), when players
make party they see all HP bar but if there is a assassin who do
cloaking or hide skill his HP bar is disable, normaly a simple refresh
work but here not...

 

I would like to know how to enable HP bar under cloak/hide skill for the party player.

 

Thanks for help!
