I bought Upgrade Etchings, but they are not in my Resource stockpiles. Where did they go?
When you purchase a Special Offer that contains Upgrade Etchings, they will not be automatically added to your Resource stockpiles.
If you want to be able to use them, do the following:
1. Go to the Resources section of the Smuggler’s Den and open the Upgrade Etchings tab.
2. Push Hoist!
