[OPEN] Sim walks down into terrain when using stair on low foundation [ Edited ]

[BryonyRae]

Has been reproduced on multiple lots and does not seem to be lot dependent.  Steps to reproduce:

1. In build mode, draw a room.
2. Bump foundation up from none to 1 level.
3. Add stair out one tile from wall.
4. Add door to wall in front of stair
5. Have a sim enter the room - no graphical issue
6. Have the sim exit the room back out onto the lot - sim will step down onto ground and then take a couple more steps and bump down into the terrain and then another step or two, bumping back up out of it.

Note that if you move the stairs in flush with the wall, the glitch may or may not occur.

When using stairs, specifically walking downstairs, I will witness sims walking into the ground for about ankle-deep and back up. It is almost like there is one more step down and back up situation.

And I thought I was the only one! I observed this when Sims arrive at the Karaoke Bar in San Myshuno's Fashion District (there is only one stair down to enter the bar, but Sims step down a second invisible stair into the ground).

I noticed the issue only in San Myshuno's Fashion District Karaoke bar (the premade one). I'm not quite sure when this started to occur, but I know it's not been like this from the beginning.

Just tested this in my game, and yes, there appears to be a problem with this lot.  I will be adding it to our list of lots with elevation problems here and will merge this thread in.

Video of the problem on the San Myshuno Planet Honey Pop! lot with pre-made building.  First, as-is, with the one-step-up foundation:

Next, if you remove the foundation completely:

Sims are sinking on the floor when they go down stairs like this:

It looks like the animation is late.

This happens indeed at the Honey-Pop Karaoke Bar with its strange "podium stair" behind the entrance (as shown in your video - I don't know how they built this).

There is an easy fix: Remove the stair and put a nice black carpet in its place. It looks the same and Sims will enter without sinking into the ground.

@alanmichael1 This is happening in the other lots that have a stair with one degree too. It really is a problem, before it was not so.

Ah okay, I see! The podium is just a normal single stair. This is indeed a problem. However, this bug is already several weeks old - I remarked it at the San Myshuno Karaoke Bar in May or June I think.
