atm iam more worried about the QA,then anything
it looks like beta -> release,all over again, this change is overpushed,and not beeing talked to us first.
best example , ether,they didnt even notice ,that they remove the resources for ether.
there are way more items of that kind,where it doesnt fit, and if mobs dont drop it anymore,it would be no help,if alches still could use the old recipes..

エーテルが作成できなくなってしまう件について、開発チームに報告しました。
プークの翼については、1.19に間に合うよう早急にドロップしなくなるアイテムから、
除外するよう対応を行いますとのことです。ご報告ありがとうございました。
I have reported the above to the dev team.
For Puk Wings they will make quick change so item is removed from the list of items that will be removed to make it with 1.19 patch. Thank you for reporting.
simple said, they found one item, but if not pointed to,they miss many other
this patch wont be helpful, but hey... they have to stick on time,instead of thinking all thru,right?
