Minecraft Forums

So basically I'm trying to install Mo Creatures onto Feed the Beast. I know I have installed everything correctly. Yes I did install the GUI API and the Custom mob spawners (Forge is already installed). Whenever I open Minecraft an error occurs at the Mojang title screen. The error log is below. I know it's a problem with Mo Creatures because when I disable it everything else works fine. Any help would be MUCH appreciated!

probably conflicts with other mods but i kinda have the same problem as you at the bottom of the crash report it says 30 more...... mine also crashes when the 30 more thing happens but when i open it with other mods no longer installed it doesn't work but when i do it without that one the 30 more thing goes away ill look into the 30 more thing sorry if this doesn't help

If you want to install Mo'Creatures into FTB Launcher, it's actually easier than you think.

I wanted to do the same thing, did a YT search, and found this! =]


P.S. OptiFine has a problem with invisible lava/water flow (basically you can't see any lava or water except the source block) so to fix that, you update the forge built in with FTB. Here's a post on how to do it, I quoted the nice fellow that ran it by us step by step.

Good Luck!

If you want to install Mo' Creatures into the FTB Ultimate pack I have created a package for you that might help. all you need to do is download the link and follow the instructions, I have all the mods in a one download thingy. If you have any trouble just send me a message over the forums and I will see what I can do.
