ME:3 All Money Gone

Lost all my money except 18.5k after Sanctuary. Nothing at all in the story about losing money or anything else, it's just gone.

I redid the mission, exact same choice (there's only one) - have my money this time. Definitely a bug.

Seems to happen if you die while autosaving - happened to me, and the game acted like I'd passed the area it saved at (all enemies dead even though a few had been left) rather than making me do it again. Apparently at the cost of all my money and medi-gel.
