Plugin stopped working after adding more lvls

The plugin stopped working but only after another increases in lvls. I was at 5 lvls the then decided to add 5 more lvls to the quarries, so then at 10 lvls. After I did that the plugin said it's was loaded but would not respond to commands, tried to reboot plugin to no success. Had to revert to the 5 lvls that work fine. This is 10 lvl config.

QuarryComputer.json

Is there a limit on how many levels this plugin can handle? I've run the config through a validator and everything and it says it's fine but why won't it work? 

Hi, should not be a limit, I will test you config today.

Thank you been racking my brain as to why it didn't work. 

Hi, found the issue on the config:
 

[Quarry Computer] Item 'mlrs.rocket' does not exist.

Change to ammo.rocket.mlrs

[Quarry Computer] Item 'economics' does not exist.

Change to Economics

Changed Status from Work in Progress to Not a Bug

Thank you I been trying to figure this out I did that config pretty late at night. So lesson learned don't config stuff when your half asleep.
