Auto booting after a minecraft restart

I have a problem where I have multiples turtles running, but when I close minecraft and return to it, the turtles have shut down. What I want to do is something that when I load the world, the turtle boot by itself and the programs run automatically.

Thanks.

This is a known longstanding bug with no known fix. If you are closing MC via the window instead of using "save and return to main menu" then that will not be helping.

Though, that bug may not have anything to do with your problem - have you actually implemented startup scripts?

I have implemented startup scripts, so when I boot the computer, the program start automatically, but the problem is when I close Minecraft. I want it so my program runs after a restart of Minecraft. Because I am doing a quarry with a turtle and it is long to dig all the way down to bedrock, but I don't want to let my Minecraft opened for hours.

Intended behaviour is that any system which was running when its chunk last unloaded, should automatically boot again when that chunk next reloads. If that's not happening then you're encountering the bug Lupus mentioned.

Some users have reported that closing their server window using the X caused this for them, and switching to the "stop" command corrected it (or using the "save and quit" method Lupus referred to, if playing SSP, though this bug typically hits SMP players). However, in all likelihood you're gonna have to keep booting the turtles manually; some users have worked around the issue with auto-clickers (eg TE's Autonomous Activator), but that's not a practical option for moving turtles.

Unless what you mean is that you want a quarry program to resume where it was when it was unloaded. That kind of functionality has to be coded into program. There are some like that on forums.

EDIT: Never mind you explicitly said they don't turn on at all. Sorry bad at reading today.
