If a computer is removed pre-load (for which ever reason), ComputerCraft doesn't sanity check to see if it's still a computer, and not been removed.

This bug was fixed a while ago, which version are you running?

1.75
And is all computer load methods using sanity checking now, or just this one issue?

A lot of fixes were made between 1.75->1.76. If you can reproduce any
crashes in the current version, feel free to report them here. Closing this
one as solved
