Mod version detection?

[latias1290]

I'm pretty sure that when you have mods for different versions installed in your mod directory, FML will detect which mods are for the currently loaded version of Minecraft and only load these. So if you have Flan's Mod for 1.7.10, 1.8, and 1.9 in the same mods directory in the same .minecraft folder, launching Forge for MC 1.8 will only cause Flan's Mod for 1.8 to be loaded, and the other two to be ignored. I always have a few profiles that run from the same directory with my standard mods that I use to enhance my Minecraft experience a bit, for different Minecraft versions, and it always worked fine.

 

But just now, I was cleaning up those profiles, and it now, it doesn't work anymore. I can install 1.7.10 mods only and launch Forge for 1.7.10 and it will work, and the same goes for 1.8 and 1.9. But when I install mods for all those versions and launch any of my Forge profiles, it crashes.

 

Why does this happen, and how do I fix it?

It works as long as the mod tells us what version is it for.

If the modders doesn't give that information we can only assume it's for the current version so we have to try and load it.

Side not, you should use the version folders to sort your mods.
