@tutley I don't know. @logan please post a photo of the one you saw today.

This instance the heatsink fan was working, however the customer reported thermal errors including a runaway.
The photo below you can see where the filament swelled considerably, so much so that it took the shape of the printed part around it.
(Some had commented that those look plier marks, but upon closer inspection its the layers from the extruder body)
