Agreed, but this means that someone has to apply an SetInteractionStatus(false)
if an interacting interactible is stopped. I think there is something missing
because anywhere else in the IS similar behaviours are automatically stopped
if an object becomes inactive.
Is this an action point? I think fixing this during the revisal of the
interactible classes would be a good idea.

I don't think that the notes says something about automatic time-outs. It just
mentions the posibility to implements something like this.

Very best regards,
