Foreach - ball - 20.02.2016

I have very weird problem with foreach. Sometimes values in Player iterator (array Player@YSII_Ag) changes automatically and this make a big problem. I don't know why this happens, I log every Iter_Add/Iter_Remove function related to Player iterator, but few seconds later some values in array changes without my interference. In callback OnRuntimeError I print full array and these values really change. Server logs:

As you can see some values changed 3 seconds after Iter_Add function. I don't know why the heck there are values like 122, 105 - array size is 51 (iterator size is 50). Line 5628 is foreach definition

Код:

foreach(new playerid: Player)

There is callback OnRuntimeError

Код:

public OnRuntimeError(code, &bool:suppress)
{
	static bool:first_crash;

	if(first_crash == false)
	{
		new s[512] = "Player:{";
		first_crash = true;

		for(new slotid, size = sizeof Player@YSII_Ag; slotid != size; slotid++)
		{
			format(s, 512, "%s%d, ", s, Player@YSII_Ag[slotid]);
		}
		strcat(s, "};");
		print(s);
	}
}

I have definitely no idea why this happens, I will appreciate every (rational) post.

Re: Foreach - Pottus - 20.02.2016

You are probably not using iter safe remove in a loop.

Re: Foreach - ball - 20.02.2016

I don't think so, because only place where player is removed from iterator is OnPlayerDisconnect, so if multiple players had left the server, there would be log "Somebody has left the server".
