EDIT: Please see below post for a fix to this!

Playing on a desktop using Firefox.

When I checked on my wolf, Curie, the nest shows she is ready to give birth. When I click the button, it displays the following message:

I tried logging out and logging back in, and clearing my cache/cookies/etc. No dice, still gives me the same error. When I check her profile status, it still says nesting. I think this is a visual bug but one nonetheless. I'll update if her status changes and I can birth the litter.

Just an update that her status changed to ready to birth and I was able to acquire the puppies. : )

Super late but I did find a fix for this:

My timers were all busted at exactly 2 hours. My PC's timezone was also incorrect, 2 hours ahead of my actual timezone, with me setting the clock manually. After I fixed the timezone to line up with my clock, all the timers (including the nesting one above) got fixed and no longer displayed incorrectly or spit out errors.

If you are experiencing similar troubles, try seeing if your PC's timezone is incorrect and fixing that first!

@Rhulk Thank you for the report. The Bug Index has been updated to include this issue.
