from memory:

WC reset point is on the left side of the caves. when going up past the snakes, if you jump down the ledge to the bottom, everyone resets. it doesnt reset on the right hand wing (with the plants and flying serpents). so you can pull there, jump down, heal, and wait for the guys to come running after you.

in SFK, if you jump off the wall into the courtyard, things will reset. do not jump off the wall.

in SM Lib, mages and others will reset if you run too far. its annoying, but thats just how it is.

i've never had anyone reset on me in RFC though.
