a few of my females pregnancy has been 'done' for a few hours now but theyre still pregnant and there still arent any babies lol.. ive had it take a few minutes before but never a few hours.. 

Same here, also with taming. Seems to be a bug...

Thank you for reporting!

Unfortunately, we encountered a server problem which shut up several crucial processes. All of them are rebooted now, so the game clock is working as expected again.

We're very sorry for the inconvenience!
