This is my villager I dragged her to eat the magic frut then she had a baby that was 4 days ago, and still the same baby today 400 minutes and still age 47 I wonder if she has the golden childs dna 2 weeks ago she drink the magic liquide which made her 4 years old from age 37. All my other villagers that were younger than her now are older.

She won't stop nursing the baby until she reaches the age she was when she drank the liquid. That's one of the side-effects of that vial.

She did not have a baby then, she is 48 now and still 400 minutes nursing baby

It doesn't matter if she had a baby then or not. Whenever a female villager drinks that vial, and later has a baby, she will carry it until she is the age she was when she drank it.

I just realised what you ment, even if a villager was not nursing a baby so if she has a baby at 18 and she was for example say 70 when she drink the liquede then she well nurse the baby until shes 70.

I had a whole village nearly starve to death because of one of the vials. It caused two villagers to switch places and one of the villagers was my Master Farmer. Well, turns out the new master farmer, after the switch, disliked swimming and parrots. The poor guy would panick and run away everytime he went near the ocean or the garden. Took me a while to figure out what was happining, and most of my food storage was gone by the time I could train someone new.

It was completely hilarious to me, but I felt bad for starving the little ones.

Yes, that is exactly how it would work!

My villagers randomly pick up rocks and carry them about with them. They carry them no matter what they are doing. Also, my Master Builder found the place on the beach to dig in VV I, and immediately built a scaffolding for a hut. Now he just digs away to no avail, so that last puzzle will never be solved!

Maybe he's digging for treasure?

The 'embracing' scenario is very familiar. I would assume you have someone set to 'parent'? When you set a villager to 'parent' they will pick one person to stick too, so when that one parent is on the move, the 'chosen' one will know it and it will either say 'waiting for someone' or 'embracing'.
I find this to be a pain, since the one 'chosen' never seems to get any work done!
I find lots of glitches. I just pick up my villager and drop him/her again and they go on with their business.... lol
