There’s some bizarreness going on here.
I posted in the English are healthier than Americans thread, but seemingly made a grammatical error.
I went to edit the post, but in the edit screen it appeared correctly (ie: of the problem), so I clicked submit and went back to the thread, but lo and behold, it still appears as “in the problem”.
I’ve tried the edit thing a few times, but it still appears correctly in the edit screen, and incorrectly in the thread.
