I see this error

Hello and thank you for your great plugin, however since my update I am getting this spamming in console

[BackPumpJack] Quarry at (-806.4, 4.4, -1742.9) as no valid matching in _datafile

This is part of the validation code added when plugin try to refill quarry.  that quarry either has vanilla loot or nothing mined.
Is there anything special about this quarry ?   was it place before the plugin was installed ?

Normally, the plugin store data for each quarry and the survey crater
For some reason, that quarry does not have data associated with the plugin. 

Simple fix is to remove the quarry and replace it. 
I could also add a command to regenerate data for these quarry.

Yes the quarry it was in place before the plugin update, Ive been using BackPumpJack for approx 5 months now.

The quarry is a players 'placed' quarry over a mine shaft. I will try to remove it and place it again, see if that helps

Very odd, I removed the Quarry, and replaced it with a new one, reloaded the plugin

o.reload BackPumpJack

Previous version of the plugin should have generated the data in datafile.
This is why I added the print in console this update, I suspect there is an issue sometime, with some quarrys with no data.

so should I load the previous version then? 

You can use previous version to avoid the message in console. 
The message is there to indicate something strange with that quarry.

it can stay for now.. see how it holds up after the wipe

is there any way you can add codelocks to your plugin to secure players quarries?

Since there are other plugins to do that, and its not relly the scope of this plugin, i dont plan to add this kind of functionnality.
