All knows that the 1.8 update had glitches. Many have been fixed, many have not. I found another glitch needed to be fixed. No not added can activate redstone or open any doors/trapdoors/fence gate. Please consider fixing this. Everyone is bugged by this .
This might actually be something with the Plots plugin - we can look into it (the penguin is back now! )
It's just something about the plugin. I will talk to the author and see if he can make a config option.
Actually, there's already a solution for this. It's as simple as adding a permission... if they were working correctly... (thanks PEX and obama)
