Recently, many of the mods I've downloaded which feature custom audio have seem to not work properly. For context most of the locomotive mods feature at least four or five distinct sounds: A start up sound, a running sound, occasionally a higher rpm running sound, an accelerating sound, and the engine being turned off. What's been happening is that certain locomotives are not playing the proper sound for acceleration, instead playing the sound of the engine starting up as a different speed option is selected. I'm not an expert on modding or what goes into a mod, so I'm turning here to see if anyone can help. There's also a recurring problem where mod audios seem to just not work at all for no reason.
