@Dune-jr could you explain the reason behind it? Also what are those changes in the submodule?

Is it to avoid spawn kills on a new round?

@ChillerDragon I proposed this to jxsl, he said he was "too lazy" to write it, and proposed to PR it; so I did.

The submodule change is a mistake, m ybad.

It's to allow people to not react for a few seconds when they are dead, instead of being spawned almost instantly and dying.
