Help! Weird script bug

[Sardinia 10]

I have a hostage rescue mission im trying to play with my friend, works fine single player. But whenever I try to play with 2 people the script activates automatically after about 10 seconds ingame and releases the hostage while teleporting player 2 to his location.

Using this script

// execute with in units initline.
// _null = [this] execVM "Hostage_male.sqf"
// hostage
_CivnotRescued = true;
_man = _this select 0;
_man setcaptive true;
_hostageact1 = _man addaction ["Untie","hostagevars.sqf","(_target distance _this) < 2"];

while {_CivnotRescued} do {
_num=(ceil(Random 3));
if (_num==0) then {_man switchmove "civilsitting"};
if (_num==1) then {_man switchmove "civilsitting01"};
if (_num==2) then {_man switchmove "civilsitting02"};
if (_num==3) then {_man switchmove "civilsitting03"};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
sleep 1;
if (not(captive _man)) then {_CivnotRescued = false};
if (not alive _man) exitwith {_man removeaction _hostageact1};
};

_man removeaction _hostageact1;
_man disableAI "MOVE";
if (alive _man) then {
player attachto [_man,[0,-0.9,0]];
player setdir 0;
player switchmove "AinvPknlMstpSnonWrflDnon_medic";
sleep 3;
player switchmove "AinvPknlMstpSnonWrflDnon_medicEnd";
sleep 1;
player switchmove "";
_man switchmove "SitStandUp";
detach player;
sleep 2;
_man enableAI "MOVE";
// just put // before this if you dont want the unit to join your group
[_man] joinsilent player;
};

I figured out why it teleports. But not why it triggers in the beginning when running multiplayer
