Describe the Bug

During the transition from the entity that moves to the blocks that sit in the world normally, the player is able to fall through the elevator blocks/contraption.

This results in players getting to the top of an elevator shaft, only to fall through the elevator back down, or to be stuck partially inside of the blocks at the bottom, causing camera jitter, extreme slowness, and the inability to move from a given block.

I've only noticed this since .4A, so I presume that is when this issue was introduced.

Reproduction Steps

Make an elevator with a floor only one block thick, and try to ride it up or down, when the contraption turns back into 'normal' blocks, it can sometimes result in the player falling through them.

Operating System

Windows 10

Mod Version

0.4a

Minecraft Version

1.18 (And 1.18.1)

Forge Version

38.0.17 (and 39.0.5)

I've artificially shortened the travel time here to make an example. When doing the full length of the shaft, it'll produce the error more frequently.

I've been able to replicate the issue on a fresh 1.18.1 instance with the latest forge, Create, and Flywheel as the only mods present, so this isn't caused by something out of date, a bugged world, or a mod conflict.
