Can confirm. I had the Linux version of Valheim installed before 2025-09-17, with valheim_Data folder.
After the game update on 2025-09-17 which renamed the folder to Valheim_Data (in both Linux and Windows versions), my local install still has valheim_Data
Verifying the game files does not change the name.
Related #577, but important to note this affects updates, not just verifying
