The virtualLevel VarTransmitListeners are only called for Sailing on login and after teleporting.

After switching in game tabs I see this debug I added triggered

	// For some reason, the script is ran on the parent container after all the skills. Ignore this
	if (idx < 0)
	{
		log.debug("Running on parent container - early return");

Immediately after the virtual level disappears from sailing and VarTransmitListener is only being called for Attack through Farming.
