Slow developing bug.

well i know that most often when you think you did things right but find issues like that it can be a result of somewhere along the line you made changes and forgot to uninstall one of your mods before doing it.

the best way to be sure is delete all mods in jsgme and replace them with fresh new copies from backup files or new downloads. then delete the entire data folder from sh4 programs folder and replace it with your backup copy of it. if you never made one then uninstall and reinstall the game.

after all this you know everythings clean and uncorrupted so the only thing left is your mod. go through it carefully and check all your settings but it would be best to begin anew from a fresh clean start if its not too much trouble.

if the problem returns then it is definately your mod, but i doubt it because if somethings wrong it usually works or it doesnt but i havent seen things that change on there own.
