Mine's been having a completely different issue.
At first, operation was completely normal and no barrel issues to be found. After a while though, as soon as I power it up and press the activate button, my wand would restart! Like I was powering it back up. Startup sound would play, lights would flash, and the barrel would retract. Then it started doing the restart cycle during firing.
At first it would only do it once in a while and after a while (a few months) it started happening more often. The startup effect would also repeat.
We tore it completely apart and found that the cable assembly going to the AUX jack in the rear of the handle had been pinched during assembly and one of the wires was almost completely cut, barely making contact so we replaced it.
Because of this issue, I think I blew out my first Matty adapter board with sound from Spongeface and now that the cable assembly's been replaced, the second board seems to be holding up just fine but the restarting issue is still sticking around, even with a fresh set of batteries.
