Bug description

I don't know what is happening. I see this error in the console occasionally. I don't think it's happening when someone is making a purchase because no one is in our market area when it occurs as far as I can tell through the console.

Steps to reproduce

N/A

Expected behaviour

Expected behaviour is that there are no errors in console.

Actual behaviour

Errors in console randomly.

Other information

No response

Can you download the latest version of 1.8.4.2 from Spigot? There was a patch fix for this a while ago that should fix your issue. The original 1.8.4.2 build had this bug and I removed and reuploaded. Please reopen if this still occurs after that
