Same error here 

@Papi Rusty @Pepuni. 
Does this happens always or just one or 2 times, it might be furnacedata issue. I will check it asap

From time to time it appears on the console, a priori within the game the plugin works fine, but there is that error

it reset my entire config btw. i had to revert for now @Iftebinjan
