NHF – new heroes for Heroes V 3.1.

Everything is bad here)))
But why is it different in the multiplayer version?
Is it to prevent desynchronization?

Added after 43 seconds
Then, make it sleep(time), where time is higher if it's a single-player game?

Added after 2 minutes
For example, I tested sleep() and sleep(0.1), and sleep(1)
The first one sometimes doesn't have enough time. The second one is good, the third one is too long))
Does it really discard the decimal? Something is wrong here. Multiplayer.
