I've posted three suggestions in the last week, gotten a confirmation email, but they don't show up in the list. I've tried manually typing in the URL, but they fail with an error page. My last one was 1050. Checking, 1047 is there, but nothing after, so it's not just me, but also not everyone, since my first was 1025, and there are other entries within that range.
I've reported to aha.io, as request by the failure page, but thought I should warn people to follow up with their suggestions.
Edit: heard back already. They say it's on Construct's side, so I guess this is now a query why my ideas aren't showing up.
