Alchemist supply missions require double the crafts

I haven't seen ANYONE comment on this anywhere yet, but it's odd that Alchemist would be singled out, so here goes.

Since the recent update, all GC hand-ins for alchemy have doubled. No longer content to accept a single craft, it will now always require at least two separate crafts. Items that are created in sets of 3 will require 6 total to hand in. Items which are single craft will now require two to hand in.

This is wildly inconsistent with the rest of the GC hand-ins where universally all other crafters can simply complete a SINGLE craft to hand-in. It also doubles their respective costs to do so.

I can only assume this is a bug, because I can't find any information in the patch notes and there seems to be very few people even discussing the matter.
