That one Tuesday where EVERYTHING went sideways on a commercial install

I was doing a DMP panel swap at a 3 story office building downtown and the old wiring was a total rats nest from the 90s. Took me 6 hours just to trace 12 zones because someone used the same colored wire for everything. My helper accidentally snagged a 24V wire and shorted the whole keypad bus, wiped my programming. Has anyone else dealt with a previous installer who just left zero documentation?

Ever find a pile of wire nuts behind the drywall?
