Steps:
1) I joined Coil with a preformed group of friends in game.
2) We entered Binding Coil of Bahamut Turn 1
3) Defeating the boss, I skipped the cut scene and the two loot chests were opened.
4) First item was for BRD.
5) Second was the Allagan Trousers of Striking
6) I was the only Monk in the party and need rolled the Trouser and kept waiting for the item.
9) After I thought I won my item (heard music but didn't check Armoury Chest) I exited Turn 1 like most of the party had already done.
10) I opened my inventory to equip my new armor piece to discover that it was not there
11) I had an extra slot in my armoury chest as well as space in inventory.
12) no error message was displayed, but was told as I exited that the item was not attained and it rot in the chest.
