Undead have a 10 minute timer for underwater breathing, and the "breath" mirror stop decreasing somewhere after 2 or 3 minutes (normal breathing time?).  If you get out and in the water quickly, it will refresh at the right time and restart decreasing.

The same problem occurs when refilling the breath bar (I.E. the bar refill 2 or 3 minutes then stop refilling, and you must get in and out the water again to let it refill completely and disappear).

What steps will reproduce the problem?
1. Grab an undead character
2. Step in the water to make the breath bar appear
3. Stay in the water for more than 3 minutes
4. When the bar stop decreasing, stay in the water a little longer
5. Get out of the water for a second or two, then jump back in

What is the expected output? What do you see instead?
Well the bar should decrease completely or increase completely.

What version of the product are you using?
r10-release

Do you have an error log of what happened?
