I was building my automatic sorting thingy at my server when i found out that you can't use buildcraft pipes on safes and thought: well that makes sense. but it still annoyed me. so i thought well there should be a config about it somewhere. but it didn't existed.
So what i suggest is that 1. add a config for that. but i get that it would only be off om white list server. so the time spent on it may be wasted 2. make it so that you can add items to it atleast
