Shrines: Multiplayer bug

We have experienced the exact same bug for months.

When doing maps in multiplayer (2 players in my case), the shrine buff is only applied to the player who clicked on the shrine - definitely over 50% of the time.

We tried:
- Standing as close to the shrine as possible.
- Clicking on the shrine while moving around it.
- Facing different directions.

Nothing works.

Please can this be fixed - many times it has resulted in deaths.
