I have found another bug that occurred after the patch went in. Last night, before the patch, I had both of my guild weekly quests ( “[Excavating] Get Sad Statues” and “[Hunting] Get Rough Leather”) in my quest journal. I had started the hunting one but had not started the Excavating one.
After the patch, both quests are now gone from my quest journal, which means the progress I made last night on the hunting one is gone.
