Title is the quick version of what looks like a routing issue
So I have a family of four sims on Moonlight Falls that I've been playing a few days. The house they're living in was downloaded and placed before I created them and they're the first family I've had live in the house. It came empty, i furnished it and apart from some issues with the spiral staircase (resolved by building a normal stair case) there hasn't been an issue. Then this morning one of the sims couldn't use any of the toilets in the house, she got stuck in the bathroom waving her arms around at me. I assumed something got in her way, moved her using moveobjects on and set her on her merry way. Then a racoon knocked over the garbage bin and made a mess of the front yard- when I sent her out there the same thing happened and I couldn't get her to walk anywhere or perform any action, just staring at the tipped garbage bin. To test what was going on, I moved her out of the way then tried to get her housemate to perform the same action and I was met with the same result. Reseting the sims doesn't work, moving them only works for so long before something invisible blocks their path and they start carrying on- everytime they go outside they get stuck. They're also doing weird things like walking through walls/closed doors, or walking down the stairs where there are no stairs. The funny thing is it's only effecting the adults from what i can see.
Darn witches.
*To note I have no mods, I use cc, all expansions excluding show time are installed and some of the stuff packs, but not the latest patch.
So yeah, anyway, I was wondering if anyone had any suggestions? Moving to another lot seems like the most obvious, which I've avoided up till now because I'm pretty proud of their house. How ever if people think that's the best solution I'll give it a try.
