Chroma unselectable/end game screen blank [CLIENT]

So i've noticed this happening every now and then were chromas are unselectable and if you change skins and then go back to the chroma skin, the last skin's name will show up instead of the actual skins name (ill try to get a ss of this asap also this is on blitzcranks skin, not nami so all chromas are broken?). Also after this happens it causes the end game screen to be totally blank
