One other thing...if the patch removed Rumphy's ability to respawn, then it ADDED a bug to the game, because according to HPI, the respawning of Rumphy was by design, not a bug. He was specifically placed in the Crypt as a character "trainer", much like the Murphy's Ghosts waaaaaay back in Wizardry 1: Proving Grounds of the Mad Overlord.
(I must have battled those ghosts at least 500 times or more! Not exaggerating...in fact, I may be understating it.)
One more reason not to use the patch unless absolutely necessary!
