Twisted Treeline Runes Bug (Consistent)

There was a bug in the twisted treeline map that made the runes I took on shyvana not show up in the loading screen (keystone and secondary tree were both black), and and when the game started my runes were were the pre built rune page: "resolve: the colossus". It was a custom game with friedns so we restarted the game a few times, each time i made sure i took the right runes and the happened consistently. and all my friends had their right rune pages as well...

The runes I took: Primary precision with Leathal Tempo as my keystone and Overheal, Legend: Alacrity and Coup De Grace as my lesser runes. My secondary tree was inspiration with Future's Market and and Cosmic Insight.
