ComputerCraft 1.73
Forge 10.13.2.1291

When labeling a turtle and attempting to place it, we encountered this crash:

This error is indeed strange, as the crash only occurs when one particular player places the turtle.

Any input would be great!

Thanks in advance!

This has been fixed, look down a few post.

I apologize, we were under the impression that our version was ComputerCraft 1.73, but apparently this is not the case.

Locked as resolved, thanks for clarifying your version number!
