Error in console

I don't know the circumstances under which this error is appearing, but I just noticed this in my console window when I wasn't on the server:

Hey! Sorry for no response, somehow i read that and forgot to answer.
It's hard for me to check what happened. Does the problem still appear?

Yes, it's still happening, but I just updated to the new version so I'll wait and see if it appears with that version.

The only problem that i can see from the code is one of my faults, but it shouldn't cause this bug. It will be fixed in next version, but are you sure that there is no other plugin that can use quarry output storage? If the problem will happen again please message me on discord ThePitereq#3979 we will try to fix this problem without spamming here.,

Hey! I made few changes in code that maybe fixed your issue. Hit me up if the problem still appears.

Changed Status from Pending to Closed
