Look screenshot ‘Play Animation’ Task has disabled,but when I delete ‘Play Audio At Position’ Task the ‘Play Animation’ Task Display state change to enabled,but in fact ‘Play Animation’ Task is disabled!
Thanks for the report. This issue has now been fixed for the next version coming up.
Unfortunately until the new version comes, the only real workaround to that problem, would be to temporary add a 2nd task and explicitly re-enable the “Play Animation”, then delete the 2nd task. In the new version this is of course handled automatically.
