If they haven't suppressed it I think it's on me :/... I think I have accidentally clicked on "remove this submission" while scrolling on my phone to check the comments (I wanted to show them to someone). I didn't get any dialog box to confirm though so I didn't realize it... I checked and it seems that it has happened before to other people and there is no way to restore it... :'((
There should be a confirmation box but since I'm on firefox on mobile maybe that's why I didn't get it, or maybe it passed to fast for me to see it while scrolling? Idk.
Huh I'm a lil sad and very sorry for my teamates :/...
But thank you both for replying so fast, that's very sweet of you <3
