Having the same issue. We have no mods installed. As far as we can tell both the local version (Build: 8781039) and the Project Zomboid Dedicated Server (Build 8781046) are both up to date. Still getting the same error:
File doesn't match the one on the server
media/scripts/weapons/sounds_deserteagle.txt
C:Program Files (x86)\Steam\steamapps\common\ProjectZomboid\media\scripts\weapons\sounds_deserteagle.txt
Is it possible to manually update the files? Our dedicated server is running on Windows.
UPDATE: Was able to fix the issue by copying the ‘scripts’ folder (all files) and sharing via discord to all players.Each player then had to copy the shared files and overwrite the ‘scripts’ folder locally. So far no instability issues.
