Infinite breath

Infinite Breath: When swimming in the water, breathing is regenerates

I can confirm this, with more details.

If the player is perfectly still, breath is consumed as normal.

BUT if the player is in motion for any reason (sinking straight down or swimming) then the breath meter flickers constantly and gets reset to maximum.

It looks like what would happen if player position updates reset the breath state to "open air" before the next check for still being underwater happens.

Confirmed.
