triggering two animations with one tap

this occurs while in INTERACT mode tapping on an element that should trigger two animations simultaneously. One animation begins with no problem but then this message is thrown.  i tried it again after clearing cache and rebooting and the same thing occurred.

An application error occurred while attempting to perform the last action.

Restarting InteractBuilder is recommended.
