Bug in filling up word strength bar (Spanish tree)

[Skye07]

My "Plurals" word strength decreased, I did 3 to 4 timed practices to get it back up (it was only 1 block from full) but it still hasn't filled up again although I've strengthened all words and on the page itself they're all full word strength.

I then tried "Nature" and that one did get back to a full bar.

This is probably a bug?

Thanks for letting us know! We'll take a look. We're working on how word strength is calculated.

It seems to be only that one that doesn't want to fill up though.
