Heyo

When you are in the Rolling Machine Interface, items do not show there name when you hover over them.

this is the case for all railcraft guis

I remember fixing something like this.
You need to add the following to the gui classes:

@Override
public void drawScreen(int mouseX, int mouseY, float partialTicks) {
	this.drawDefaultBackground();
	super.drawScreen(mouseX, mouseY, partialTicks);
	this.renderHoveredToolTip(mouseX, mouseY);

}

Fixed in one of the recent commits.
