Good! Some folks would have tossed the board for a new one. Better to repair than replace.
While the RUMBA is 'open source' it's not very friendly. It's designed in Altium (I can't imagine how expensive a seat is), so you can't open the files to generate a BOM. :(
Honestly, you really don't even need that diode - it's just there to protect the electronics in case of a polarity reversal. But a few cents of insurance is worth it.
When that diode fails it needs to fail-closed, otherwise it would allow the reversed polarity into the downstream circuit.
Just be careful next time you hook up your wires. :D
