kyna.js and intrdoction.js timestep correction

As the title specifies.

file kyna.js. In Kyna bj scene there is no "world.TimeStep" call, is this a desired thing?

Point of the situation:
Files that have yet to be verified are:

equine.js
feline.js
lizard.js
magnus.js
room69.js

For the file "lizard.js" there is no "world.TimeStep" call, if fact the time advance after the encounter.
So I do not know how to proceed here.
The same applies to the file "equine.js". To be honest did not even know that there were some sex scenes with them before looking at the code. My character is too strong ..
