Even if I log out in survival, I am converted to creative mode every time I log in, sometimes after survival mode for a split second before. It also happens when I go to the twilight forest and nether, I'm willing to bet the end and any mystcraft worlds too. It started happening after the first time I used NEI's cheat mode, I think. I tried editing my clientside NEI.cfg to have the wrong command to change my gamemode, but it kept happening. It also keeps happening after I deop myself. The only thing I can think of is that maybe the serverside NEI just really wants me to be in cheat mode or something. As it stands right now, I just have to spend a second to type /gamemode 0, but I often forget before breaking a block or flying and wondering why I don't fall. If a fix requires me to be unable to do cheat mode, I'd be okay with that. But is there any fix?
