Blueprint working in editor but not in Vive ? ? ?

Hi guys I’m currently working on a Window Washing game project which involves heavy interaction using the HTC Vive.

I am currently having an issue with getting a specific blueprint to work. It is basically an event where if a bottle of bleach falls into a bucket of water it changes colour and spawns Bubbles. This works in editor but not in the Vive so i was wondering is anyone knew the answer ?

Thanks
