Thank you for pointing out the February change log. Indeed, we have announced that the collectibles would respawn every 8h back then.
However, please take into account that we're working with a live product and changes in various game versions are bound to happen. Moreover, it is very likely that the "Collect all" quest depends on the zone shutdown as well (see this dev blog for more details).

I wish to have no conflicts with the Brazilian community, so let's try to calmly discuss it without inferring wrong conclusions about one another.
