This problem occurs because you dont define which instances you want to pick, so all instances change their color:
First: You change the animation for all charm_multiply2 with charm1=15 and for ALL (no exception) charm_color2.
Second: When a charm_color has color=1, ALL charm_color2 change their color.
I deleted the container and on the layout I assigned the charms to the appropriate groups (via instance variable 'Group_ID'). Also i improved the events under the "CHARM" group (i hope without bugs ;).
