New Update Glitches

I'm sure you've heard it all before this post but highlighting again the current issues I am facing in my game since the new update. 

1.) Not being able to use a pregnancy test after 'Try for Baby' interactions.

I know there is a fix to this by checking whether your sim is aging or not, but isn't very effective when you're trying to do a vampire legacy challenge lol

2.) Highschool Years

Still experiencing severe glitches when trying to go to school with my sims. If I travel with more than 1 sim, only 1 of them will show the tasks for that day. I have also been stuck with my sims in copperdale a few times (which is hell no harm). It's really annoying when this is a pack i have paid money for and it's just broken. 

3.) Infant/ Toddler Glitches

This is one I have encountered everytime i age up my sim from a infant to a toddler since the new update. either the toddler sim will act in ways the UI for Infants would function (E.G. feeling gasy or glitching down to infant animations). I have also had a few issues when uploading Toddler Vampire sims to the gallery as it's showing them having a 'Dark form' which obviously they don't have prior to becoming a teen. 

I know these issues have definitely been raised before but any advice would be great because i really don't want to corrupt my save files. I only have MC Command centre installed but only after the update.
