372	Critical bug in Elevator	Peter Kovacs	Balazs Dezso	"The attached code fails on the attached input file. It runs `Preflow` for all node pairs, but for one of them, it gets in an infinite loop. Using `LinkedElevator`, however, it works correctly, see the commented lines.

It seems that calling the `deactivate()` function of `Elevator` does not deactive the node, so it will be selected again as the highest active node."	defect	closed	critical	LEMON 1.3 release	core	hg main	fixed
