Issue: Game fails to launch during preloading when loaded alongside Lumy's Skin Patch and in a mod folder exceeding 42 mod files. No, I am not making this up. Note that if library mods are included, the magic number is 48.

If you want a list of mods I can provide it, but after hours of testing different permutations of my mod list, I cannot say which, if any, other mod in particular besides Lumy's, AM2 + AnimAPI, and AM2PG causes this crash, only a sufficient number of other mods. Also note that bundled mods like Buildcraft, if using an all-in-one jar file, still only counted as one mod for the purposes of exceeding the magic number.

If I find anything else I'll update this post, but I've been testing this for hours and haven't managed to come up with anything definitive, only what I've stated above.

Well uh...
LumySkinPatch just have some strange mcmod.info file, but crash will be fixed in next upd.
For now, you can specify AM2 version in AM2PG config and that will prevent crash.

general {
    # Supported values: [Undefined, Mithion, ToCraft, kutschkem, TCLProject].
    S:AM2Build=Undefined
}

Change Undefined to whatever you playing (only Mithion, ToCraft, kutschkem, TCLProject supported).

Thanks for the prompt assistance, that worked a treat. If you don't mind me asking, what was the ultimate issue causing the failure to launch? I only ask for curiosity's sake - I've never seen a mod conflict occur with a specific number of mods installed (if indeed that was the cause.)

Well, that was only cuz of LumySkinPatch mcmod.info file, and doesn't matter how many mods do you have.
Thing is, I'm parsing through entire loaded modlist, and forge sorts that list... well... idk how, exactly, but it DEPENDS on how many mods do you have.
And when it's time to read LumySkinPatch mcmod.info file, mod crashes.
So, if I read AM2.jar first, it will not crash, but if I read LumySkinPatch.jar first, it will.
Totally pseudorandom, depending on mods installed in sepcified folders.
