I think it's a bug. What is your device and game version?
I have the same issue using HTC Vive with game version 0.5.0. It's almost like it sends the input twice, connecting and then disconnecting the object.
Thank you for reporting. I'll look into it.
Vive and version 0.5
Thank you. I can't confirm it in my environment, but I fixed the code that seems to be the cause in v0.6.0.
