Mining turtles like to disappear?

Tekkit Classic Server/Client
I have had 2 mining turtles disappear, and this is a costly thing, when trying to play legit.

The first time it happened I logged of the server while it was running the mining program I wrote.
I then tried to make it happen again, and what happened was it mined one block higher then it was supposed to do.
Third time It was mining with a new program, as the inventory wasent big enough for all the different types of blocks it could pickup…
And I walked away to goto my chest, and came back and it was gone! I tried it again to make sure it wasent something wrong with the program, and it wasent.

Thanks,

I would also like to say I had to make 2 accounts for this forum, as my hotmail account would not get mail, but gmail did.

So that's MineCraft 1.2.5 with ComputerCraft 1.33?

I can tell you that I've never seen this sort of thing happen in recent builds, with the exceptions of when the server crashes while a turtle is moving or when a tree decides to grow over them.

Whether or not your issues have anything to do with the versions you're using is difficult to comment on without seeing your code.

Is this in single player or on a server?

Mining turtles aren't exactly costly.
Show the code please.

It is 1.2.5 minecraft and 1.33 computer craft

it is a server running tekkit classic

I hope you mean this code XD

function mine()
for m = 1,80 do
  turtle.dig()
  turtle.up()
  turtle.dig()
  turtle.down()
  turtle.forward()
end
end
function back(number)
for a = 1,number do
  turtle.back()
end
end
mine()
back(80)

The only reason I'm playing classic tekkit Is my friend's computer loads a black screen on tekkit normal if any1 has input on that :D/>
he also says classic has some things that normal tekkit dont.

I once get stuck under a natural cobble generator, using a knight tower mining program. That can happen when there is a lava lake over a water lake. There are issues like this one that are not easily reproducable. If you can, go where the turtle was supposed to mine.

Server crashes or chunk unload maybe? Even if it does not disappears, a turtle will stop if its chunk is unloaded, which may happen when you go away..
