On the patch notes released on Jan 21st, it was said that:
"
Fishing
Updated Bait names to specify the water type they are associated with. This is also reflected in the bait wheel when selecting which bait to use on a given fishing hole.
Fishing holes in the Clockwork City and Artaeum areas can now provide trophy fish when using any bait other than Simple Bait.
Fixed a rare issue where, despite feeling a tug on your fishing line, reeling it in would result in catching nothing. Now, whenever you reel in your fishing line after feeling it catch on something, you will always obtain something."
(Emphasis mine. And as a side note, the issue wasn't rare) I made up a char and went fishing, since someone had to try it out. I was planning on spending a few days trying to figure out the rate of furnishing drops, but I don't think it will be necessary. On my second hole I had the bug happened to me 3 times in a row. I was in Windhelm, fishing by the docks(?) using worms with no add ons active.
@ZOS_GinaBruno , please let the people in charge of this fix know that whatever they did is still not working. TIA.
