Detective Achievement not registering in Tatari

A user reported that they did not get the Detective achievement in Tatari.

Here's their global.dat for debugging: https://cdn.discordapp.com/attachments/471379035113652254/602905414509658142/global.dat

I also did not get this in Tatari, nor did I in Himatsubushi. Waiting to hear back from that player's results when they finish that arc.

此 issue 涉及一個 C# 遊戲專案中的成就系統。請檢查成就追蹤邏輯，該邏輯很可能位於處理 Tatari 劇情線進度的腳本中。首先定位 'Detective' 成就的觸發條件，並檢查提供的 global.dat 存檔檔案中相關的標誌位。確定條件未滿足的原因，並確保成就完成後能正確觸發。
