Yes, it’s hidden for the reason I mentioned earlier: forum users don’t decide what counts as a bug. The Anvil staff reviews posts and moves confirmed cases into that category.
For example, I’ve reported some that were clear bugs like this and others that could have been intended behavior like this.
It’s up to the team to decide which ones belong there — that’s why the section isn’t directly visible to everyone.
Another reason is that once a bug is fixed, the post no longer helps future readers, while regular forum threads remain searchable and useful for anyone encountering similar situations later.
