Household member turned neighbor while still in household

As the title states, my sim who has been in this household for many sims months, has three kids with his fiancee and is most definitly in my household suddenly got the "neighbor" role as I started my game this morning. Haven't played with this household after the latest update. I have no cc or mods and have never encountered this before. I haven't tried to move/merge any household (this or any other) and i havn't had a neighbor visit for a long time. If I have this sim chosen I can make him do actions as usual, but if I play from his partners perspective I can only "invite in" or "open profile". With testingcheats enabled I can only "reset object" and "cheat needs". Noticed when I made him take out the trash and he could not enter his own house again. 

They are all in the same household in manage household and cas still.
