"tongue_pull_stopped" "choke_stopped" events are inconsistent between versus and coop

[ProjectSky]

• If kill smoker while being caught by the tongue, release_type should return 3, but never return 3 in versus mode (this code work in coop)

function OnGameEvent_tongue_pull_stopped(params)
{
    ClientPrint(null, 3, "tongue_pull_stopped, release_type: " + params["release_type"] + "\n");
}

function OnGameEvent_choke_stopped(params)
{
    ClientPrint(null, 3, "choke_stopped, release_type: " + params["release_type"] + "\n");
}

is this a bug? I remember it worked for me before the update.

release_type 3 will check tongue_break_from_damage_amount convar, damage less than this will not trigger. but in vs mode this value set 300, tongue only has 250 health, why should it be set to 300?
