The Duplicato bug is still here

Before I start, I am aware there was a thread for this, but it says fixed but I just did it on an up-to-date game. I was visiting the realm of magic and had just learnt the duplicato spell. I used and didn't think much of it, I proceeded to leave the realm of magic and got on with my game. A couple of in-game days later I was looking around my neighbourhood at the fishing spots and I saw a familiar face, me. I went to interact with him and got confused. I proceeded to use the spell again to check if there was something I was missing, but this clone disappeared. I befriended and invited him into my household and he had the same skills, magic spells and rank. The only difference is that the clones inventory was empty. I went to CAS and recoloured his clothes so I could tell them apart, and tried to replicate the bug.

I went into the realm of magic and tried again, following what happened the first time as the clone in my neighbourhood vanished without a problem. I did this not once, but twice successfully. I checked the site and it was set as resolved and patched, so I tried updating my game just in case, but I was up to date, and did it again.

Steps I took:

1- Went to the realm of magic

2- went to the basement and talked to a sage

3- mid-conversation I duplicato'ed 

4- talked to my duplicate and got the friendship bar up a little ( he was also talking to the sage)

5-used the go-to home button on my sim portrait and left (I was using Transportale spell if that helps)

6- when I got home I could call sim to lot, although that aside they appear to have a sleep cycle

They didn't appear in households, mine or other as far as I could tell.
