I'm using SmartMenu (methodmap from Menu) that have AddItemFormat method (very useful) and SmartPanel (methodmap from Panel).
My problem is that menu/panel can't translate phrase via client index (just throw error like "Translation failed: invalid client index 1431192909").

This problem seems to appear only on SmartMenu and SmartPanel methods that use VFormat.
Example:

public Action CMD_Test(int client, int args) {
	SmartPanel hPanel = new SmartPanel();
	hPanel.SetTitleFormat(_, "%T", "CMD_TEST_MENU_TITLE", client);
	hPanel.DrawItemFormat(_, "%T", "One", client);
	hPanel.DrawItemFormat(_, "%T", "Two", client);
	hPanel.SendToClient(client, PanelHandler_Test, 20);
	delete hPanel;
	return Plugin_Handled;
}

Log:

SetTitleFormat method source:

public void SetTitleFormat(bool onlyIfEmpty = false, const char[] text, any ...) {
	char sTitle[MAX_MENU_TITLE_LENGTH];
	VFormat(sTitle, MAX_MENU_TITLE_LENGTH, text, 3);
	this.SetTitle(sTitle, onlyIfEmpty);
}

Also i have problem with some HEX strings (colors). For example i have KeyValues config:

"Senior Member"
{
	"color" "006400"
	"kills" "6500"
}

I have tried to debug and then console said "sName: Senior Member | HEX: 6400 | Kills: 6500".
Why 6400 instead of 006400?

This also appears on 9400D3 (output: 9400000) and 4D7455 (output: 1.#INF0)
