[1.7.10] Modpack crashes

[Roadhog360]

My modpack crashes the game on phase 7, at stitching textures. I have no idea why. The same exact Forge, mods, and configs all work fine on my default launcher. Why is this crashing?
I don't understand at all. I am inclined to believe I did something wrong although everything appears perfectly correct. I need this working ASAP.

Suggestion: Use more than 1 GB RAM. 2-3 GB based on the mods list.

1GB works fine on the normal MC launcher.
(I've also already tried adding RAM to no avail, same crash.)

Also, why would you suggest 2-3GB? It's only 24 mods. 2-3GB is what I use for around 150 or more mods.

UPDATE: It turns out FastCraft has a very specific incompatibility with my mod for an unknown reason.
If FastCraft is enabled, setting the mipmap at 4 would crash the game. This is the default setting so any client, by default, has this issue.

I have no idea what causes it. I didn't change anything special or anything about rendering, or mipmaps. I just added blocks and items. But anyways since this was an issue I didn't know about my mod, this thread is no longer relevant.
