So last Wednesday, I made a change which I thought might have fixed the doubled word adding bug, where if you pressed the manual add word button, sometimes you'd get the same word twice in a row. Has anyone seen this bug since then?

Nope.

Not recently, and I've been actively trying to trigger it.

Not since last week.

oh that would be so nice, my items due are too many for me to check that unfortunately....

Haven't seen it!

Phew, let's call it done! What a gnarly bug.
