What happened?

To be honest I can't really explain whats happening, except by saying that like, in certain instances, items cheated in with REI will have a bugged Item ID, making it so they cannot be stack alongside normal items. I'm unsure if this is caused by another mod, or is a bug for REI itself.

What mod loaders are you seeing the problem on?

Forge

• Visual
• Recipe Lookup
