[BLOCKING] The return of the Phantom Redstone.

Partner Rank: 1

Partner Team Reporting: Noxcrew

Verification builds:

1.6.0.15_R6_RC4

1.6.1.0_RC0

Summary:

When the second player is teleported to an unloaded part of the world, Redstone components are not functional in a way that is consistent with Phantom Redstone (MCM-109). Buttons do not function, and repeaters do not take or pass a signal. Breaking and replacing these components makes them work properly again.

Impact:

The player is unable to use any Redstone mechanic if a second player teleports to the area first, where the Redstone is situated. This prevents Noxcrew’s Grid Runners from being played under these circumstances. Other buttons non-essential to gameplay are also affected, which is confusing to the player.

This is also a wide scale problem for any future content, can impact every aspect of the store.

Repro Steps:

1. Load up Grid Runners from the store. (Make sure it's version 1.0.5)
2. The first player starts the map and does nothing.
3. Let a second player connect (This player should spawn in the Introduction lobby where the first player is)
4. The second Player presses the ‘Press me to start’ button
5. Wait 10 seconds
6. The first player presses the ‘Press me to start’ button
7. The first player goes to the start button for the IRON course (location 279 81 571)
8. Press the button to start the IRON course.
9. Observer the button is not functional.

Observed Results:

Redstone components are not functional when a second connected player teleports to a location. Specifically, the buttons and repeaters described above.

Expected Results:

Redstone components should always work.
