I have a bug - the sirens are not working. Cars spawn usually with siren off, but even when you press the siren button the sirens don't work.
I installed Project Nostalgia as a standalone mod on a clean Em4 install. I've tried it as a LA submod, as a standalone, and a standalone with LA mod's audio files. Anyone have a fix for no siren?
EDIT: Fixed. If you have no siren or siren, or other issues of assets/things missing try what I did:
1. Completely delete the mod from your mod folder.
2. Re-download the files from the mega(dot)nz. My first download was corrupt. The files you download for this submod should contain stuff like a text file/pdf for a userguide, credits for the mod, and an in-game logo for the mod. If these are missing, your files may be incomplete.
3. Re-install as a stand-alone mod, not a sub-mod of the LA Mod.
I did this, I got the full files, and my game has been mostly fine since! So something could screw-up on the mega(dot)nz download so try again (even if mega(dot)nz is already downloaded and you click save again like I did the second time).
