Over on GTM I posted a video of a glitch I noticed with the 03January build. Can you look at it?
By any chance did the 08January build fix the problem?
I just tested it and it STILL gyrodances around. I think it has something to do with the motor. Maybe disabling the motor after what is attached to it breaks off will fix it.
EDIT: But the spinner physics are AWESOME!!!!! Spinner mass reduction of 25% is super realistic.
EDIT 2: Shouldn't spinners spark when they nick the floor?
