Bukkit

What steps will reproduce the problem?
1.  Every hunt, whether manual or automatic
2.
3.

What is the expected output? What do you see instead?
Hunt is supposed to stop at dawn, announce winners, give rewards, and end.
Hunt doesn't stop or announce winners.  Awards seem to be sporadically given, then timer resets and hunt continues.

What version of the product are you using?
MH 1.5, CB 1597

Do you have an error log of what happened?
Here's the error I got when I tried manual stop.

did you ever get a reaction ?

I'm having the same problem. The debug returns this: MonsterHunt][Debug][MonterHunt][DEBUG: - NEVEREND]Stop Time

I have my time set to the default and I turned rewards off just to make sure that wasn't the problem, but it still won't stop.
