Just had the bed throw an error again.

Code:
Recv: Error:Heating failed, system stopped! Heater_ID: bed
Changing monitoring state from 'Printing' to 'Error: Heating failed, system stopped! Heater_ID: bed
'
Recv: Error:Printer halted. kill() called!
That was all the error message OctoPrint gave me. Doesn't say if it was a thermal runaway or not.
