When multiple small bricks are cframed together to create a pattern, collision is slow and the blocks are slippery. Because of this, your legs move through the ground.
1. Does the bug happen 100% of the time?
Depends on the situation, happens almost every time multiple small bricks are cframed together.
2. If so, are there steps that reproduce the bug? Please list them in very high detail.
When a floor is made out of small individual parts (to create a pattern, multiple layers) this bug happens almost every time.
3. Where does the bug happen (www, gametest, etc)
Production, probably every version out there.
4. Is it level-specific?
No, although some levels are worse than others. Here’s an example:

5. Would a screenshot or video help describe it to someone? If so, post one.
7. When did the bug start happening? If we can tie it to a specific release that helps us figure out what we broke.
I don’t know, it feels like this has been happening forever.
