When I signed up for Beastkeeper in Febuary I set my birthday to be  30 September, but now it says my Birthday is 30 December. Is nothing major but I find it weird that the birthday on my profile suddenly changed on its own.

I've changed it back but I just wanted to point it out. I use Google Chrome and Windows 7.

Thank you for reporting.

There was an issue with birthday month not saving, I believe it was about several months ago. It was fixed some time ago so everything must work without problems right now.

Sorry for the inconvenience.
