I need help;🙏🙏🙏 I can't get the lumberjack to sell me the blueprints for the greenhouse. Do I need to buy them on a specific day? Every time I go to the forest, I can only visit during the second hour of the morning. Or do I need to buy them before triggering a certain quest? I don't want to kill the mercenary and ruin the cave quest. Please help me.
