This isn't really too big of a issue but a while ago quite a few of us noticed that upon a log-in onto the server when offline for a while will cause the pressure chambers is glitch out in a way where it they will lose air as if they are disconnected. The multi-block structure of the pressure chamber still works but it is as if they are disconnected from any connection to a [Advanced] Pressure Tube. In order to fix this issue is that you are required to break a block of the structure and replace it. I've setup a Steve's Factory Manager setup to send out a redstone pulse every 5 minutes to a Block Breaker and Block Placer setup to fix this issue without me remembering to fix it myself when I log back in. Edited in Note: Might be related to a chunk loading issue. Edit2: Just came up with a solution that will break and place a block on a login, might make a tutorial on it. I ask, do you guys have any ideas on why this happens and if it can be fixed? If not, do anyone know of a way to get a single pulse from some sort of detector when you log onto the server to break and place a block. Thanks in advanced.
You could create a setup using the player detector and the pressure tube to break and replace if you are online and if the system has no pressure.
That was the solution I came up with Booker, just that I am curious to why this is happening though. Edit: Using a Universal Sensor with a Dispenser upgrade to detect if I am online and using a piston to send a one tick pulse to a Block Breaker and Block Placer with a tick delay on the pulse to the Block Placer. Tested it with people in my island and without people in my island, seems to work like a charm.[DOUBLEPOST=1426656125,1426617944][/DOUBLEPOST]Update: After testing and testing... managed to break functionality of a couple of my machine while relogging a ton lol. I conclude that universal sensor will not work because the chunks unload soon as I log off and the sensor never gets the chance to detect that I go offline. If there is a way to detect that I'd love to know.
