Hi,

Since a few weeks ago, I discovered FTB and I like the Unleashed version of it.
I'd like to install the Jammy's furniture mod, but it crashes every time.
Here comes the crash report:
---- Minecraft Crash Report ----
// I'm sorry, Dave.

Time: 12/24/13 3:58 PM
Description: Failed to start game

java.lang.RuntimeException: Tried to recreate an item id (5000 / shifted:5256) for an item which already exists as net.minecraft.jammy780.furniture.item.jfm_Items@2056c454. Check your config and resolve the conflict.

That's an ID conflict.
Tried to recreate an item id (5000 / shifted:5256) for an item which already exists as net.minecraft.jammy780.furniture.item.jfm_Items@2056c454. Check your config and resolve the conflict.

Moved to Mod Discussion. Tech Support isn't the place to post about adding things to FTB.

Thanks. As you may have noticed, I'm new on this forum. :)

BTW. The problem has been solved. There is no need to help me anymore. :p
