Since updating Utilization Monitor Blargh from 0.8.7 to 0.8.8 (and Factorio from 1.1.35 to 1.1.41), I'm getting this error each time I move an entity with Picker Dollies :
Script @stdlib/stdlib/core.lua:46: PickerDollies:The mod Utilization Monitor (Blargh) (0.8.8) caused a non-recoverable error.
Please report this error to the mod author.
