The bug

Spelling mistakes in the 'Commandblock chain tried to execure more than x steps!' warning message.

Should be:

Command block chain tried to execute more than x steps!

How to reproduce

1. Set the gamerule maxCommandChainLength to 0

   /gamerule maxCommandChainLength 0
   

2. Place an impulse command block with one chain command block behind it
3. Power the impulse command block
4. Look at the log
