Losing Warzone RP Boost

A match had just ended for the Mythic Warzone Firefight. I used a RP Boost after and immediately got put into a another game which just ended in a loss. I come back to lobby and see that I’ve lost my boost. This has happened multiple times to me. Please fix this.

You were put in as a join in progress, jip. Your boost will be added back to your inventory after a couple of games, if you were not given any points for it. At the end of the game, you can see if there is a boost score. If the boost score is 0 your boost was not used and it will be added back to your inventory.
