Thermistor in common ground

Hello people!
There is any problem if I connect one terminal of the thermistor to the common ground and then use just one other wire to connect it to the board?
I have a quickfit setup and installed a common ground to reduce the wire/pin count.

I'm having thermal runaway and cant find the reason :(
It is happening randomly and I still haven't managed to cause the problem on purpose.

Thank you.

    So far the problem has not appeared again since I had unattached and reattached the Arduino Mega to RAMPS board, maybe it was some bad contact there, but, not sure yet.
