Re: Sims can't go upstairs
So I tried what you suggested with both my modified version and the original creators version, and both worked when I took out the custom content. I saved the vanilla lots and loaded it into my original game with CC and it still worked, but the stairs were still an issue when I loaded in the original CC lots. That being said, I think you’re right about invisible CC blocking the path, but I’m not sure how to get rid of it.
I repaired the game (didn’t work) and then tried to click the entire area around the stairs to see if I could select/delete any hidden objects but that didn’t work either. I tried looking at other forums to see if there was a cheat for revealing invisible objects or obstacles, but I only found a stuck object remover mod that sadly no longer works.
Also, I’m not quite sure why the stairs didn’t load for you. The build used base game stairs haha. But I did replace them with a different set of stairs too (just in case) that didn’t work either.
Thank you again for the help!!
