To make the computercraft/cc: tweaked turtle do anything like breaking blocks, I asked the Dev of cc: tweaked for the fakeplayer ID. I gave [ComputerCraft] all Stages but its still not able to break any blocks. Same Problem with buildcraft quarrys. At startup the logs tell me that all stages has been loaded for [ComputerCraft]. So any clue what I am doing wrong or is this a bug? If you need more info, let me know and I'll post it here.

This is what my gameStagesFakePlayerData.json looks like:

[
{
"fakePlayerName" : "rftools_builder",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName" : "rftools_elevator",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName": "[IF]",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName": "[ComputerCraft]",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName": "[Buildcraft]",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName": "[Mekanism]",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName": "[Minecraft]",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
},
{
"fakePlayerName": "[Modular Routers]",
"stages": [ "zero", "one", "two", "three", "four", "five" ]
}
]

The name is ComputerCraft not [ComputerCraft]. https://github.com/dan200/ComputerCraft/blob/914df8b0c7cc28451ea56a53808024511ff52642/src/main/java/dan200/computercraft/shared/turtle/core/TurtlePlayer.java#L29

I should have mentioned before that I tried ComputerCraft as an alternative and it still didn't work.
I have the same problem with Buildcraft and I tried both spellings (Buildcraft and [Buildcraft]). The Quarry from Buildcraft can't destroy blocks either.
