I installed electrum a while back and noted down the 12 word seed. Haven't used it for a few months, but now when I go to view my seed (clicking on the seed icon on the bottom right of the GUI), it asks for my password, and then the dialogue says:
"Your wallet generation seed is:"
And the text box below is completely empty, underneath which it says:
"Please write down or memorize these 0 words (order is important)..."
A bit concerned my seed seems to have vanished. Any suggestions?
