Since there’s aparantly no one from Memrise staff on the general forums I’ll leave it here.
There’s a serious bug in Memrise timing algorithm for reviewing items. Maximum review period is capped at 180 days. That’s a serious problem for those with thousands of words for review - no matter how good you know the word, it will always come up at least twice a year, making it impossible to use Memrise after a certain point just because of the time you would need to review the words.
I know that I can ignore the word, but it would take a lot of time anyway and there’s no fast way to do it. And I don’t want to do it anyway - I want to keep reviewing the word, but make it 360 days, 720 days and so on.
This has been numerously reported, since years ago on an old forum. But so far I do not see any comment on this issue from anyone the Memrise staff.
