Hello, after 25 active years of coding, Ive never encountered anything comparable to what happend today. Using the Adafruit Motorshield v2.3 on the UNO, connected to 4 DC-motors, there were so many "bugs", which are absolutly impossible to happen. But they did. Like a boolean variable was not set…

Arduino behaves non-deterministic?

Or your code is riddled with bugs. Post your code, in code tags.
