1.16.0.210.05

Summary:

We tested the command: /execute @a ~ ~ ~ tp @s ~ ~ ~ into it, set it to "always active"

Then tried to move around.

We successfully moved around on the following Minecraft versions.

Minecraft Version: 1.16.201.01
Minecraft Version: 1.16.210.05
Minecraft Version: 1.16.220.51

We thought it might be the return of this bug ~~MCM-1206~~ that broke A Nightmare in Candyworld and sent the player spinning off into the unknown. But Candyworld is not broken by this, Dinosaur Dig and projects that are currently in progress are affected by this new bug. Here is a clip of the bug in Dinosaur Dig.

Impact:

This breaks some of our maps because the player is able to move around, breaking immersion. There is also a chance that the player will not be able to pay attention to the cutscenes and miss important information presented during them.

Repro Steps:

To reproduce this bug simply follow the steps in the provided map linked in the Notes section below.

Load the provided map Kable’s Bug Test World
The player should be facing the command block with a switch underneath.
Flip the switch.
Try to move around if you are able to move around if so then this proves the player is breaking the command to hold the player in place.

Observed Results:

I entered the command /execute @a ~ ~ ~ tp @s ~ ~ ~ into a repeating command block and was still able to move around freely.

Expected Results:

The player should be held in place unable to move.
