Stardew Valley is a unique game with no set expectations. The player is free to do whatever they want which I thought was cool. Sorry to hear about your recently planted crops! I always get stressed when scheduling and timing have to be perfect to reap the rewards so whenever I do play Stardew Valley I'll often stick to the other hobbies/skills as there are no real time constraint to worry about.
Glad your next harvest went well though! Thank you for sharing your adventure.
