I just had three moms give birth with nursing times of 480 minutes instead of 240. The population only went up by one with each birth, & they are only holding one baby each so I don't think twins having anything to do with it. The "nursing for:" minutes are going down at a normal rate. Any ideas? (Note: speed is set to 2X, but it was before too when beginning nursing times were only 240 minutes, and I haven't messed with my computer's clock.) Thanks in advance.
