T1 Sabatoge stuck?

[(NSW)xDarkWolf17x]

So I am currently doing a tower 1 sabatoge, my first attempt at a void, been sitting here for over an hour trying to figure out what I did wrong. I went through the void portal, killed the 2 bosses, Lotus says to pick up the key, but there is no key? Is this a known bug, and if so is there a workaround? I'd hate to have spent all this time and effort to lose it all now....

This happens a lot with the Grineer bosses from the Void Sabotage. They sometimes don't drop their key. It's a loss, can't do anything about it except quit.

Rare glitch very annoying. Try having it happen when you finally find the Mantis part in a rare Orokin cache fml...
