Blew bench switching PSU, did I make a mistake probing?

I wouldn't have expected the probing (although no use for any practical measurement) to destroy anything.

If one MOSFET was forced into conduction at the wrong time something must have blown somewhere, either that or the coressponding gate drive has been destroyed.

Were you using a 1:1 probe? AC coupled scope?
