In the latest release, when fish spoil in your inventory it counts as you crafting something and therefor will count towards the achievement of lazy bastard which I do not think is an intended thing but a bug.
To replicate track the lazy bastard achievement and have fish in your inventory and wait the time for them to spoil.
(this was done on multiplayer so people do know that)
Spoilage counts as crafting
Re: Spoilage counts as crafting
Thanks for the report however, no it does not.
If you want to get ahold of me I'm almost always on Discord.
