It seems the Second Chance exotic armor for the Titan spawns the character in with only 1 shield charge, though it's meant to grant 2. This issue isn't as egregious as the Icefall Mantle bug where it eats your ability charge on respawn after death, but certainly worth mentioning. Though the second shield charge begins charging up as soon as the character's feet touch the ground, I feel like not spawning with 2 charges is a bug that would be best brought to your attention so it could be fixed. Then it would be in-line with other "twin charged ability" exotics in the game. Thank you!
