[KCD2] I missed the guaranteed sketch and now I’m in investigation hell.

I missed the armour sketch 5 that you can get after the alchemist quest and I’ve spent the last 20 hours doing investigation quests hunting for this to randomly drop in a bandit chest. It’s getting a bit exhausting now. The bandits are easy to defeat but I’m on hardcore so no fast travel, I’m consuming more honey than a bear to stay alive (doing lent) and I’m running back and forth to my forge and getting more exercise than real life.

I know I don’t have to get the sketch but I’m going for all trophies in game and DLC so I don’t have a choice

Just needed a little vent about how long it’s taking to find this sketch.
