Hi,
It's likely a problem of logic inside your Fsms, and not a PlayMaker Bug.
Make a simple scene with a cube, and test a single feature, the mouse down for example, if that works, then you'll need to compare this with your other scene and setup. I know, it's a pain, but we all have to go through this... You could do some logs as well in the state you think you are reaching or not reaching to make sure of where you are when built.
Bye,
Jean
