They CLAIM that the all gold stat was a bug and that this is a bug fix.
They do not seem to be aware of this "fix" let alone the "bug" beforehand, there was no indication of foreknowledge anywhere.
It could just be a case of the devs not telling Oasis anything
Or a case of dev/Oasis being too lazy to fix the bug so just claim that it's intended behavior
Or a case of underhanded dev/Oasis tactic at selling too essence, and are lying about the bug/fix thing--If the change came at any other patch, it would not have been so su*ious. But the EXACT same update that introduces tool essence? Well, you can draw your conclusions.
But in any case, no, they would not be changing it back.
