Crystal Lens / Glass Lens

[Lin Bug]

Is anyone else having trouble getting more Lens after beating the last boss? I'm trying to get one last achievement and finish upgrading some bottles, but I can't get Lens to drop from hitting the glass jars. Or am I forgetting to gather them from somewhere else?

It might help to equip memories that increase your luck, such as A Different Path (the memory from Bailan's memorial), or increase the chances of harvesting higher tier resources such as The Small Stuff (Concord's memory from gathering 30 resources).
