Minecraft Forums

Basically, I'm a new modder (I'm new but i know how to install jar files but just to clarify, I'm not THAT new) and I loaded like 21 mods into Minecraft but it kept crashing even before the Mojang logo appeared! Help me! (Forge 1.7.2 - 12.10.1.1061)

I have these mods below:

1. Forge 12.10.1.1061
2. bspkrsCore v6.8
3. LuckyBlock Mod v5.0
4. AnimatedPlayer v1.4.0
5. BattleTowers Mod
6. Mo'Creatures v6.2.0
7. EmeraldMod v3.2
8. Familiars Pack (API, DefaultMobs, ExtendedFam, HerobrineFam)
9. FoodPlus v2.8PRE4
10. Minecraft Comes Alive 4.0.1
11. MoreSwords v2.6.2

13. PennyArcade v1.0 alpha
14. RadixCore 1.0
15. SuperEnchants v0.4
16. Too Many Items
17. UpdateCheckerMod

Please help me ASAP... I can't figure it out!I really need help! I'm starting to get bored with a normal 1.7.9 Minecraft vanila blocky world (Even though i do have MCEDIT)... That's why mods were created! But.... C'mon! Minecraft is letting me down even though the crash report says i get "a token for one free hug at my nearest Mojangsta".... (I don't even know what it means, it sometimes also says stuff like "You should try our sister game, Mincecraft!")... Any mod expert out there? Please?

I had this problem too. I fixed it by: one by one I uninstalled the mods intill I had found the mod that was causing the problem.
Maybe you installed a mod incorrectly.

Good luck

Mo's creatures requires two other mods, that I think may be on the download page. That's all I know. I'm a new modder too, even with 27 mods installed and counting.

I would try to post the entire crash report but I can't copy the report straight from the launcher and the only way was to open the Crash Reports files in '.minecraft'.

Quote from tulir293

A modder (mod developer) or just installing mods? If you're a modder, read what sirtyler13 said.
If you're just installing mods, make sure your forge version and minecraft version match up and that you don't use any mods that aren't designed for the specific Minecraft version.. Don't use 1.6.4/1.7.2/1.7.4 mods with 1.7.9.

I just download mods...

The crash report file only stated below: (It didn't say the exact thing from the launcher...) (It didn't have the lower part)

What other two mods? Tell me please...

Quote from tulir293

Did you make sure that you aren't using any outdated / too new mods? If you use Minecraft 1.7.2 (which you should be using with that version of forge), make sure ALL the mods are specifically made for 1.7.2.

Yes

Quote from grimallq

Mo Creatures requires Custom Mob Spawner mod.

Ok... Thanks.... I now need to download that....
Tell you guys if it works after i test it

Ok... Like you guys asked...
Entire crash report:

(After downloading Custom Mobs Mod)

Ok... Thanks...

Quote from grimallq

You should have done this from the start, now everything is clear.

That's a Minecraft 1.6.4 mod, remove it. It has not been updated to Minecraft 1.7.2 yet. I'll admit someone might have noticed it earlier, but not everyone remembers which version which mod is for. The crash report makes it obvious. That's why you should always post the entire file.

Thanks guys, it's finally working properly! But... (I may sound like a noob when i ask this) how do i turn of cheat mode from "Too Many Items" Mod?
