Not sure if this is a bug report or not.
Typically, I’ve just been typing in numbers instead of writing them out because it’s a whole lot easier. This has always worked until today. I came across 二斤. I wrote “2 loaves,” and it let it pass, but with a spell-check error. (you’re answer is a little bit off)
I did a search and found that in the past, the spell checker made typing in the numbers impossible, but I’ve been typing in many of them over the past year, so I assume that’s “fixed.”
Any way you look at it, it seems odd that it would accept it with a spelling error. This has me wondering if numbers will be accepted for other counters or other vocab items going forward?
