Pollination success?

The Cryptocoryne cordata ‘blassi’ pot was getting a little too crowded, so i repotted it. Apparently, the ‘fruit’ didn’t like that move and it melted into mush the next day. Now I’m beginning to wonder if the pollination was successful or not. The fact that the ‘fruit’ not only survived for 14 weeks after the flower died, but also grew leads me to beleive the the pollination was indeed successful. Gah! No more repotting.
