Sometimes you just have to bite the bullet and reload.
It's just a part of gaming.
I lost 19 hours in a game once because my cat stepped on the power strip power button.
Lost 3 the other night in DKS due to being over confident and ended up getting my ass handed to me.
The list goes on...
If it's a bug..I hope they fix it.
If it's because you forgot to save...just suck it up and hit reload..who knows you might something really cool ?
I'm with you, I space saving so much some times because I'm just so into the game.
Good game Larian.
