Melted Ignition Coil? How much trouble am I in? Please help!

SWIM made a huge mistake and accidentally tried starting the engine (m54b30 w/ MS45 DME) with one of the ignition coil ground wires disconnected after doing VCG and Vanos seals, and #6 ignition coil melted. Checked all related fuses that I could find and they were okay, and tried a new OEM Bosch coil but to no avail. Is my ignition coil wiring harness fried? Am I in more trouble than I can imagine? Does anyone know how I can test my wiring harness to determine if this is the issue? Thank you in advance
