Island Race Chest Glitch

The island race extra reward chest glitch is no longer working for me. Is it still working for anyone else?

This was where you would complete the last race level on PVP mode and then open a red troop purchase offer on the top left of the main screen and upon closing it would take you to the island race completion chest collection screen again and you could claim the reward again.

Let me know if it is still working for you.
