[BUG] incompatibility with add-on Straight Reward about fsrs4anki

[kuroahna]

@cocowash I don't think this a bug with fsrs4anki. This is a bug for Straight Rewards addon. You should raise a bug on their GitHub.

In Anki 2.1.54, the reviewer.get_next_states() method exists, but in 2.1.55 beta 1, this method no longer exists.

In other words, Straight Rewards addon is incompatible with Anki 2.1.55, and hgiesel will need to update his addon for it to work again.

Although, if you're using fsrs4anki, you shouldn't worry about ease anymore as that is no longer used in its scheduling algorithm. It is only used for converting an existing card to fsrs memory states. You can safely disable straight rewards addon and use fsrs4anki without any issue.

Also, you shouldn't be worried about ease hell anymore, and hence not need to use Straight Rewards addon. @L-M-Sherlock has addressed this issue (difficulty hell) by implementing mean reversion to his algorithm, see details here

@kuroahna, ty for the time for explaining why straight reward broke, since 2.1.55 still in beta I just going to deactivate the addon. Also, my reasoning behind leaving it on before this report was just for safety if one day I just decided to stop using fsrs4anki. Maybe it's just too soon to be concerned about it.
I'm closing the thread.
