What in the heck is this error?(SOLVED)

[SenkoTwiik]

I just moved a family I have been playing for a while into a new home, one that I made.
As soon as they moved in, two of the 6 family members started getting this error, and I have no idea why. I can't really understand the error files. Can somebody check it out and let me know what it means, or what could be causing it? I haven't downloaded any new hacks or anything like that.

I'm not sure how to attach this, whether I should paste it here, or attach it. I will just attach it for now and remove it whenever it gets solved, if that's okay.

If you are using TJ's Smartbeds, and put the bed in the inventory to move, clear all the bed assignments.  Assuming you didn't add any new mods or custom content, beds in particular, this is a possible cause.

I'm not using smartbeds. But I put regular ones in inventory.
I had a pet bed that was reservable, that's the only altered bed I have in my whole game.

EDIT: I figured it out. It was just a plain old normal bed that I had in the inventory. I deleted it and everything was fine.
