Excalibur Umbra as well as his blade disappeared from inventory

[MrCreepyMaster]

So i played through some quests (on of them was the sacrifice) and i wasn't really dedicating to finishing one of them. Once i got my Excal Umbra i was like "Hey, thats pretty good" and then i just forgot about him. Now i have an unfinished quest (the sacrifice, where i have to go back to earth) game tells me to equip my Excal Umbra, but the problem is that i DO NOT HAVE HIM!!!! Literally both my umbra and the blade just disappeared from my inventory, however Umbral Mods are still there. Can smn explain this to me, because now i cant finish the quest nor play as the Excal or even have his blade on me.
