You simply change the value in the propmover file which is used in the source code to calculate your speed.
This is what you have to do, to fix it!
Go in mover.cpp and search for this:
Code:
m_pActMover->m_fSpeed = pProp->fSpeed;
Code:
m_pActMover->m_fSpeed = 0.1f;
The neuz will no longer calculate the Speed by using the Value in propmover.
I know its maybe not the best way to fix it, but it works.
