Yeah. When I copy and paste the clip a bunch of times it happens every now and then.
By the way, you can also go to the properties of the rawr clip, set a duration then extend the clip in the timeline to fill that duration. It’s supposed to repeat the animation until the end when that’s done. But with both methods, the battery and corners of the crosshairs blink every so often.
Looks very cool. 
Since you been using Glaxnimate more, what do you think?
