Sleepers with 0% hearing can still hear and wake up too early

[FranticDan]

With the changes TFP have made to how sleepers and stealth work in A20, does anyone know any tricks on how to stop sleepers with 0% hearing from waking up too early?
Also, anyone know how to make stealth checks always fail? So, attack volumes always wake up.

Scenario: A boss in my mod woke up from at least a few blocks away from the sleeper volume boundary, while the player was only using melee, wearing padded armour. This boss has 0% hearing, I've also increased the amount of noise required in the xml for triggering sleepers waking up!

If anyone knows how I can prevent premature wake-ups, it will be greatly appreciated!


TFP have broken how sleepers work on a large scale!
