Pirate ship mode bug

Sometimes when I’m playing co-op with Clappy and I roll Pirate Ship mode, the cannons won’t fire and the music won’t play. This has happened twice tonight, but it’s not easy to replicate. I was playing as Jack offline before I took a break and did the co-op game. I’ve had this issue before getting Jack, so I doubt it’s the DLC that’s doing it. Has anybody else had this issue?

I had something similar happen, which is when I’m not the host in a coop game, sometimes the music and the cannons are out of sync, probably due to lag issues. Never had them be totally silent though.

It seems to happen if I’ve played solo then co-op later without restarting my system in-between. I didn’t have the bug last night playing co-op so I dunno.
