teen aged up in relationship bug

my teen sim has aged up being in a relationship and they are both young adults now, their relationship satisfaction is decreased as well as their romance bar and every time they go to do a romantic interaction it glitches and triggers a last exception with mc command centre and I had no idea what it was, I ended up having to download another mod to scan it and go onto the discord for them to tell me it was a game bug, can we please get this updated because it is so annoying.
