Linedef type 450/451 has a low latency if several actions are performed at the same time
I don't know if this is a bug or a technical limitation of the engine?
If you have several mechanisms that work with Linedef type 450 and at the same time they work at the same time, over time this mechanism will become out of sync.
That's an example. Shown here are three mechanisms that raise and lower the floor. But after a while, everything breaks down, as if there is a delay of 1 fracunit.
You can download and see how it is done and test it

(maybe I don't understand something or have done something wrong?)
