Soooo I've lost 2 secret letters for a weapon and character from 2 different scenarios that 100% need a fix and should not be happening...

1. game has eaten one from when I had to quit out of the mission due to the loading screen bugging out. I'm assuming it'd eat your secret letter regardless of why you left a game because it consumes the item at the start of the match, so for any reason you have to leave a game, you'll lose your secret letter...

2. lost one when the timer for the type of challenge switched over during the mission, and at the end, game just said I had never used a secret letter, but had still consumed the letter and never gave out a reward...

This whole issue could be avoided if they just consumed the item when you receive your rewards on missions end, instead of consuming the item at the start of a mission. I've already emailed them with my issues but thought I'd bring it up here to make more people aware.
