I played survival in the single player mode and then I switched to creative after which I then switched back to survival I could break down nothing and build nothing so I ask myself why that does not work anymore I have not minecraft a few years gambled more but still playing on the 1.8 version of so I'm wondering that it is now as described.
Is it possible that instead of surviving you switched to hardcore? Then you can only break down blocks with suitable tools.
So I entered gamemode 2
No, play gamemode 0. There's your error gamemode 2 is the hardcore mode
Not correct. Game Mode 2 is not the "hardcore mode". Minecraft is unplayable in Game Mode 2. The Game Mode 2 is called Adventure Mode or Adventure Mode. This is very helpful in Adventure Maps: Players can't just dismantle everything but only that is intended
Ok thats right. I agree with you and apologize for the misstatement. Nevertheless, gamemode 0 is the normal survival mode and therefore the solution of the puzzle
