so im attempting to add bank files in a Mod to a game that doesnt support this, using RuntimeManager.LoadBank(path, true);  
returns the error  
“[FMOD] Unable to load {0} - bank already loaded. This may occur when attempting to load another localized bank before the first is unloaded, or if a bank has been loaded via the API”  
i used a harmony patch to make fmod ignore this error, however the bank has 0 events,  
any help?

i could try editing the base bank file but i have no idea on how to do that

Unfortunately, help with modding falls outside of the scope of forum support. I’d recommend reaching out to the modding community of the game you’re modding for assistance.
