For more information see here Bug Report Template Build: 1.9.11 4131 Mode: Multiplayer (Does NOT happen in single player!) Reproducibility: Always Severity: Moderate Type: Signals Summary: Motion Sensor signal output does not update when the motion sensor is turned off/on Description: In single player if a motion sensor is turned off/on its output signal is updated accordingly. For example if you attach a light to a motion sensor and stand inside the sensor area, then turn the sensor off, the light will also turn off. This does not work in a multiplayer games and can lead to broken signal logic! Steps to Reproduce: 1) Star a multiplayer game. 2) Place a starter block of any kind. 3) Add some form of power to the structure. 4) Add a lever and give it a signal name (I just used 's'). 5) Add a motion sensor and give it a signal ('l' in my case) and set it to fallow 's'. 6) Add a light and set it to fallow 'l'. 7) Stand in the motion sensor area and flip the switch ('s'). 8) Notice that the light does not change state. 9) REPEAT the above steps except on step 4, toggle the lever.
