So uh, I was on a server owned by someone else on ftbforums, when I placed a toggle latch and activated it. It immediately crashed the server, and when I tried it on singleplayer, my client crashed. I looked into it, and apparently you need mceditor to remove it. However, I also noticed that the version if Blue Power was the second newest; maybe the latest version has it fixed. My question is, how do I contact the server owner, and tell him this? Thanks for all your help.
