If a property contains spaces in it's name, then the connected actuator won't activate.
I have to rename the property by removing spaces from its name, then I update all the logic bricks to match the new name. And then it works just fine.
But once I rename it again (adding spaces back in) then update the logic bricks to the new name, it stops working.
This only happens with the Property sensor that uses "interval" as a evaluation. All the rest of the evaluation types can use all properties (no matter what the name is)
The Blend file explains in more detail, and contains different layers that show a comparison.
Thanks
