Computers turn on when the chunk is loaded.

In previous versions of ComputerCraft, when a computer was Off and you exit Minecraft or unload the chunk and then open again Minecraft, the computer still Off.

Why computers turn on automatically in 1.481? When a computer is off and you reload the chunk it will turn on without you to start it. This can produce lag on servers.

Sorry for my bad english.

This is how it is supposed to be. If it didn't in previous versions (I assume you're coming from tekkit) then it was a bug.

Really? I had thought that only computers which were on when the chunk was unloaded were supposed to come on when the chunk was loaded again. Hmm.

Oh, I misunderstood. Yes, they should remain off.

Sigh, just reproduced. Will look into fixing for next version.

Hooray, bug reports DO work!

Unfortunately, it appears that this bug also prevents Turtles from restarting when a chunk reloads, regardless of their previous ON/OFF state. I have a row of Melee turtles in a mob farm. They attack in a simple loop, which worked fine until we updated. Now, they function until everyone leaves the chunk, then they EACH require someone to right click on them to activate them, at which point they function as normal until unloaded again.

Computers starting and not starting is annoying the hell out of me.

Temp fix: use chunk loaders to keep the area loaded :)/>

This does not work between server restarts, which many multiplayer servers do on a daily basis.

That's the issue we are running into now. I have tried a number of things to help debug this issue, the only one that seems to have yielded any noticeable results was having a turtle.turnRight then Left at the beginning of the startup program. In some cases, one or two of the turtles would be turned to the right after an unload. So, some of the time, at least, the first line is running. I'm also finding that some of them, very occasionally, are crashed when you attempt to boot them, with a "Failure to Yield" error. Hope that helps ;D

This actually sounds like an error in your code.
