If you pick up the light force (level 4 magic ring), ZC immediately crashes.
If you start with it in the init data, ZC crashes as soon as the beginning-of-quest fade-in finishes.
Looking at it just lying there on a screen is perfectly okay...you just can't actually get it. 😛
...THE INVENTORY CAN'T HANDLE IT!!! IT'S GONNA BLOW!!! *runs*
