Re: [WORKAROUND] Sims get stuck behind stairs
This only happens to me if I go into build mode while a sim is using the stairs - they will fall through into the gap below. If that's what happened to you, then try not to go into build mode until all sims have finished using stairs.
To get the toddler out, remove the wall temporarily or use the testingcheats on mode, and teleport the toddler out by shift-clicking on the ground and choosing "teleport here".
