What do u do if i accidently sold the stonr tablet that gets inserted in the cave?
Sale of plot-important items again.
There are few options here:
1. Rollback to auto save if the sale was before 3 game days (study the first sections of saves)
2. Regular purchases of goods at a pawnshop, expecting that one of the goods will be the item sold.
3. Start the game again.
All important items that you sell will eventually be available for purchase at the pawn shop. However, you need to buy other items first before they start appearing.
