After waiting for a 12-minute cooldown, it hit 0.
Then continued to count down.
It reaches -60, then resets to 0, then counts down to -60 again. All the while, my Reached The Summit is stuck at 99% and my travel weariness at 100%.
Help? D;
Edit;
Turns out it's just a display bug. After hitting 0 I presume it's supposed to disappear. Drinking wine thereafter works fine.
