Cannot comment on some sentences

[morbrorper]

Sometimes when I have written a sentence comment (intending to initiate a discussion) and try to post it, the system just answers that something went wrong, and my comment never gets posted, no matter how many times I try again.

Interestingly, it is possible to post a comment on the same sentence manually, but that’s a hassle, so I mostly just don’t bother.

Here is one discussion that I had to set up manually: Vendí mis libros barato

Update: here’s a screenshot of a comment forever lost:

Here’s another sentence comment I had to create manually: Las malas noticias viajan veloz

And another: El vestido que llevaba era más feo que pegar a un padre. I had to create it manually It shows, because the one I crafted doesn’t have the final period (full stop).
