10.2.5 Retail patch breaks some functionality

[hejchaplin]

Gladius is not updating correctly when entering/leaving arena, meaning:

• Opponents are unknown until they get out of stealth or similar (they are not displayed until they're targetable)

• • If there has been a previous arena match where gladius has displayed players, it will not be reset when entering a new arena.
• • If a target is in stealth when arena has started and previous match has been played, gladius will instead show the old players.

• Opponents are unknown while in the starting room (showing old history or if there is no history, shows nothing)

• When leaving arena gladius does not hide, displaying previous opponents (it does hide when relogging)
