The empty brush strange cage of 1.7.10 cannot be synthesized.

Unfortunately, I don't have the time to maintain this mod anymore.

In order for anyone to help, though, you will need to provide more information about your configuration, such as your modlist, the mod that adds the entity that has the problematic case, and the id of said entity.

My guess, knowing none of the above, is that the entity in question does not register its egg to Forge's central registry of eggs, so this mod cannot possibly even know it exists.

(Side note: given your vocabulary, I am guessing that English is not your first language and you're using Google Translate. This makes communication harder, especially for specifying technical issues. Where possible, using the game's IDs rather than localized names will help with that.)

Still, thanks for using my mod, and I'm sorry I don't have the time to troubleshoot it anymore!
