A few of the magazine perks have been missing from the word of crota. Ricochet rounds used to be an option to choose from the mag perks in the enclave and now that along with armor piercing rounds is gone. I used to have ricochet rounds on my word of crota adept and it has now been replaced by a grayed out alloy mag. I tried changing it to just alloy mag and it is no longer grayed out, but then i try changing it to something like accurized rounds and it defaults to a grayed out alloy mag once again. I cannot remember if it's been ever since i put my lost memento in or if this has been going on for longer. When I check the companion app. Accurized rounds and ricochet rounds should still be available to choose from on the gun but they aren't. Not in game.
