Moving out (splitting active house) stuck in processing

I am running into an issue where I cannot move out one of the kids who just turned into a young adult (after they graduated, of course).

I use the phone or computer after making sure there is an empty house available.  At that point I am able to select the vacant house as well as confirm which part of the split house will be the active one.  Then it sits on processing, for hours, until I give up and give my computer the three-finger salute (ctrl+alt+del) and force the program to end.  The town I am currently playing in is Moonlight Falls and I am playing with epic life spans active.  I do have a large house with a lot of bits and pieces on display which, I read somewhere can affect the moving process, though I do not know why when it is splitting the house and not moving the whole household.

I have had this issue before (in another town) and found that the only way I could kick the kids out once they graduated was to marry them off.  However, this particular brat is a diva with commitment issues so getting them in a relationship to the point of proposing marriage, let alone it being taken seriously, doesn't happen.  I also shouldn't have to marry the kids off to kick them out.

I have read several people having similar issues and the only solutions given were to use the edit town and split the household that way or restart them game.

I have tried to have them move out via the cell and the computer and, as stated above, it goes through the motions then gets stuck in final processing.  When I try to split the household through edit town all it does is make the active family inactive.  When I make the family active again the YA I've been trying to kick out is still a part of the family.

My computer exceeds the min system reqs, I have most of the EPs and am running the current patch, I do use Twallan mods and they are all up to date.

Any other ideas or help with this is greatly appreciated.  I currently have a full house and want to start making room so I can get the heir married and working on the next generation.  Preferably without pulling any hair, real or digital, out.
