This sentence, in the “>50.000 most common” collection, has been stuck in my review queue at 25% for some 1250 days now, which means I have to play it multiple times a day. I must admit to getting a bit tired of it .
@mike: All my attempts to edit this sentence are failing.
It’s in all browsers I’ve tried, and the app (collection not downloaded), so it must be a back-end problem. Curiously, it seems to only appear when doing Review All; unfortunately, that’s my preferred review mode.
