I see. I think the things that do have solutions should come back if anything, if there are problems that do not even have one at the moment like the rep page imo.
You mean big avatar prize? That's already back. Unless you mean the compression rate.
Only prize working as it was supposed to is sparkles. Even HTML isn't working as it was before, you need an admin to make it work if you change it, for example. And it was made pricer.
Image username? I have one and it gets invisible any time of the day. It's random like that, on and off. Imagine paying a lot for something isn't working or aren't sure that will be there for the next 6 months?! And even before the update, we were told to limit it because "no waste of usergroups".
Avatars are our biggest normal prize and it isn't working as before.
The cheapest prize that Mbxx added? No one is buying it.
So it's unlikely that Elusive Prizes comes back sooner.
