Omen of Amelioration bug

If there are more than two of these in the stash, sometimes it doesn't work. This bug has been around for a while, but I haven't bothered to report it. I just keep one in my stash, and if I die, I go back to pick up another one.

This morning, I was too rushed to finish a map boss before heading out of the house, so I didn't have time to follow my usual routine. This has punished me severely. I died a second time and lost many hours of grinding.

GGG, can you please fix this?

Thanks.
