Hello everyone, especially the support team and ConcernedApe.

I’ve run into a persistent crash issue while playing Stardew Valley Version 1.6.15 (Build 24356). I’ve tried multiple troubleshooting steps but still can’t fix it, so I’m here to share details and hope for help or feedback.
1. Crash Situation
The crash happens every time the game transitions to a new day (from midnight to 6:00 AM in-game). As soon as the new day sequence starts, the game freezes and crashes immediately, with a "System.NullReferenceException" error prompt. I can’t progress to the next day at all.
2. Core Error Info
The key error type is a System.NullReferenceException (Object reference not set to an instance of an object).

From the log, the error is linked to the "new day initialization" logic—specifically the code that traverses game locations (e.g., _newDayAfterFade method in Game1.cs and ForEachLocation method in Utility.cs).
3. My Game Environment
  • Platform: Steam (using SteamHelper)
  • Game Mode: Multiplayer (I’m the host)
  • Save Progress: In-game date is Fall 4, Year 3; crash occurred while I was in the FarmHouse
  • Hardware/OS: NVIDIA GeForce RTX 3050 Laptop GPU, Windows 10 (Version 10.0.26100.0)
  • Game Language: Chinese (zh)
4. Troubleshooting Steps I’ve Tried (All Failed)
  1. Disabled all mods (including SMAPI) and launched the vanilla game to load the save—crash still happened.
  2. Verified game file integrity via Steam; the system confirmed all files are intact.
  3. Loaded a backup save from 2 days before the current one—the new day crash persisted.
  4. Ensured the game is updated to the latest 1.6.15 build (no version lag).
5. Attachment Note
I’ve attached the full error log file to this post. It includes the complete stack trace, system information, and in-game details—this should help locate the root cause of the null reference error during new day setup.

Thank you so much for your time and help. I love Stardew Valley and really want to fix this issue to keep playing. If you need more information (like additional save details), please let me know!
