Season 7 Legendary RP Boost Problem

I was playing Halo 5 for the Xbox One and went to use my Legendary Req Points Boost I got from the Season 7 Req Pack. The game loaded me into a match that ended within 30 seconds of the last round of a game mode called Tank World (or something). Since the game mode is like Breakout, I was unable to actually play and I was unable to receive any points toward my RP Boost. Essentially, I didn’t get to use a legendary item because the server placed me in a game where I was unable to properly use the Boost.

Can I get little help here?

Hey, Grither.
Are you sure the boost didn’t work? Did you get any RP from completing that Tankworld game? Unranked playlists like Action Sack typically give less RP per game than ranked playlists, so it could be that the boost worked and just gave you less RP than you expected.
If you got no RP at all, then that would definitely be a case where the boost didn’t trigger. Also, did you check to see if the boost was returned to your REQ collection?
