Beta 4 still carries over the bug introduced in beta 3 whereby the character cannot be replaced (via an Action, Animation Behaviour) without leaving the previous character still viewable!
Hey @AndyG, I've also just experienced this whilst trying to replace character with action animation. For me, it occasionally works, but each time I preview, I see a different result everytime, so it's very inconsistent. What I can see in debug mode, is that each action stacks on top of each other, so when I collect 'Action A' and 3 seconds later I collect 'Action B', they are stacked on top of each other for the action duration and the character doesn't change fron A to B until A drops off after the set duration. I saw this when I setup a scene to quickly collect 4 different action in quick succession and I can see they're all stacked on top and each newly collected action should instantly replace the previous one. @Andy, is this bug fixed in Beta 5?
