This command to stop keyframed motion should always succeed, and never shout an error: llSetKeyframedMotion([], []); It should not shout the error "Cannot use llSetKeyframedMotion() on a physical object." It should not shout the error "Only linksets which uses the new prim equivalency system may be animated." It should not shout the error "Cannot use llSetKeyframedMotion() on an attachment." The errors should be retained when starting an animation, or resuming one, but not on stopping one. Stopping should always succeed, and always put the prim in the normal un-animated state without error messages Original jira issues: https://github.com/secondlife/jira-archive/issues/7496 https://github.com/secondlife/jira-archive/issues/13633
