So I have three kanji schedules on my dashboard (N5 through N3) and wanted to merge them together so the dashboard is less messy. Upon doing that I quickly had regrets and decided to remove the schedule so I could add them back as their own schedules, but now after adding them back I suddenly have TONS of reviews and most of the masteries have been set back to level 1..
Is there a way to get my progress back withou manually editing mastery for every single kanji or did I massively mess up?
Try checking your vectors. If you have any vectors you haven't studied, all of your kanji will look like they're at level 1. This is just a weird visual quirk with Schedules. if you check your kanji in the dictionary or Advanced Search they should look fine.
For example, If I take one of my kanji schedules and tick "Kanji radical" 95% of the kanji will show as level 1. Goes back to "normal" if I uncheck it.
