Keep rope/jetpack/parachute selected when destroyed and having secondary ammo selected Assumption: You rope with secondary ammo selected. You miss a shot, destroying the rope gear. Previous behaviour: Rope gets deselected and the secondary ammo gets selected, you can no longer rope. Very annoying, reason of many Shoppa fails! New behaviour: Rope stays selected, but selection of secondary ammo is cleared (because rope gear got destroyed). Makes much more sense overall. Analog for jetpack and parachute.
