Quoted from Groo:
In no way complaining about the bugs, but have seen a couple in .89 on the Pro. It seems that the multiplier lock is different for different characters. One will turn on the lock when pushing the button to launch, one will not turn it on, and another will activate the lock when pulling the plunger instead of launching with the button.
Also needs to be some tweaking on the Hoth shot. A faster up post to lock the ball in when it bounces off of the dual posts so it doesn't roll back down might help. Also if it does bounce back and around, and you hit it back up there it doesn't recognize it and will time out and just release the ball without letting you choose a mission.
Can confirm, I noticed both of these last night.
